Over the past week, particularly in the last few days, the crisp Internet air has been abuzz with news from the upcoming expansion, Wrath of the Lich King. Fear you're out of the loop? Here's a quick round-up of all the information being released, along with analysis and opinion.

Don't forget to keep checking back, as this page will be updated as information becomes available:

Dungeons and raids

1. An analysis on Arthas as a ten-manned event, including its impact on the 25-man raiding structure, as well an exploration of its consistency with the lore.
2. Did you know that all expansion raids will have a 10-man setting, as well as a 25-man?
3. Read through some of our initial impressions on the 10-man raiding set-up.
4. We also wrote up a concise overview of the ins and outs of dungeons post-expansion, including a new token system, similar to [Badge of Justice].
5. The Nexus has been announced on the official site as one of the new dungeons.

Zones, factions, and relevant lore

1. Alex has written an excellent overview of the Grizzly Hills, a soon-to-be zone for low to mid-seventies. With old factions reappearing, along with other surprises, it's definitely something to look forward to!
2. If news of the Dragonblight has intrigued you, you'll be pleased to know that more information has been made available.
3. While we're brushing up on our lore and learning about new areas and factions, Alex thought it fitting to illuminate the lore behind Azjol-Nerub, as the Nerubians will have their own role in the expansion.
4. Alex asks us about lore figures we'd like to see in the expansion.

Continue through the break for new information on Death Knights, as well as video and interviews, analysis, release date information, and our full-range of Wrath galleries.

Here's one more tidbit of WoTLK information for you, courtesy of Gamespy. They sat down for an interview with co-lead design J. Allen Brack. Most of the information is stuff we've heard in the past or have already posted on in this morning's massive flurry, but it's always nice to get a peek into the brain of the folks who bring us this amazing game.

Among some of the things discussed by J. Allen Brack and Gamespy:

• Flying Mounts are gone until level 77, at which point you will either complete a quest or a visit a trainer to be able to use them again. You will still not be able to use the mounts in the old world, so even though Naxxramas is on Azeroth, your flying mount will not be able to cross back over the sea to visit the old stomping grounds. The Old World was designed using too many graphical shortcuts in places people were not meant to access to allow flying mounts.
• They have recieved massive positive feedback so far about the return to Azeroth and the old traditional fantasy as opposed to the sci-fi feel of the Burning Crusade. In that same vein, they are bringing back many familiar sights and storylines from Old Azeroth. Sholozar Basin will be Un'goro 2.0, complete with crystals and pylons. No word on whether it will also contain more Land of the Lost and Nintendo references. It will also contain some of the flavors of Stranglethorn and the old Netherstorm biodomes, says J. Allen.
• In a similar vein, we can expect to see more of the ever-popular Scarlet Crusade, this time in the form of the Scarlet Onslaught. The Worgen are back in homage to the Sons of Arugal and Shadowfang Keep.
• While the city of Dalaran will be headed up to WoTLK, don't expect to see nothing but a hole in the ground where it used to be in Alterac. J. Allen reveals that they do have plans for the spot, and the concept drawings they have for it look very cool.
• The Dragonblight, J. Allen Brack said, is probably his favorite new piece of content for the expansion. It is where the Dragons were born, where they recieved sentience from the Titans, and where they come to die, and where the Lich King has been twisting Dragon corpses to serve him as Frost Wyrms, so there's a lot of great lore and history there. It will include a raid instance called the Chamber of the Aspects, and while no bosses have been designed for it yet, it will probably have bosses representing each of the Dragonflights.

It sounds like the developers are nearly as excited about WoTLK as we are, which is usually a good sign of things to come. We hope you've enjoyed all this awesome new information we've found for you tonight. There may be more to come, so stay tuned as we scour all the latest news.

Via Gamespy and Worldofwar.net, we finally have a good idea of what rolling a Death Knight will be like. A lot of the rumors seem to have panned out, but others have not. All I know is that at this point, I am full speed ahead to make a Death Knight my new main come WoTLK. There's a lot of meaty info to dig into, so let's get to it after the break.

Gamespy has five new amazing videos everyone should check out. They include several sneak peaks of things we haven't seen before. They are the most detailed and rich in-game videos of WotLK to date. The videos cover the areas of Dragonblight, Zul'Drak, Sholazar Basin, Borean Tundra, and the Howling Fjord.

There are several first looks at the new cities, zones, and architecture of Wrath of the Lich King that we haven't seen from Blizzcon. This also includes several mobs that have not been seen before. Zul'Drak is reminiscent of Zul'Gurub, and looks quite new and refreshing. Sholazar Basin is a cross between Stranglethorn Vale and Ungoro Crater, heavily influenced by Troll architecture.

We are also presented with vehicle combat in the Sholazar Basin video. This is simply amazing. The video shows a gnome flying machine contraption shooting missiles at other flying mounts, and then a gnome ejecting and floating down to safety in a parachute. Grand Theft Azeroth.

In the Borean Tundra video we see a beautiful look at the new cities for both Horde and Alliance players. There are also images of Dragon kind, similar to what players experience during the last leg of the Onyxia quest chain from pre-BC. Also included is a gnome city, much like Area-52.

Check it out now, and watch for more detailed analysis of the video and all the other news as the day goes on.

In addition to all the other info dropping today (apparently Blizzard held an event this last week at their HQ to show off some new Wrath information), GameSpy got to chat with Jeff Kaplan, WoW's Lead Designer, about Death Knights and what they're going to be for in the next expansion.

• Apparently Kaplan says Blizzard has designed "zero" raid bosses for the next expansion yet, so he isn't sure where they'll fit among Pallies, Druids, and Warriors as tanks.
• DKs will have a disease-based DoT, as well as the creature and ghoul summons we've posted about previously
• As we heard before, Death Knights will serve as a "Fury Warrior" type of tank -- damage based rather than protection based.
• Blizzard hasn't determined exactly whether there will be faction differences in the epic class quests, but they won't be too different for races or factions, just because the stories, he says, should be the same
• Finally, Kaplan clarifies again that Death Knights will be available to all races, and that Arthas himself became not Undead, but Scourge

In case, maybe, Arthas wants to come back? We'll let you read the rest into what Kaplan said -- he unfortunately didn't tell us too much new information, but he did clarify a few points we already knew about Death Knights. And the news about Blizzard's nonaction on raid bosses so far is interesting -- has Blizzard really not made any raid bosses yet, or are they just not ready to tell us about them?

Gamespy has lifted their press embargo, and there's lots of new Wrath of the Lich King info up. They apparently did a long hands-on with the expansion, and lots of new zone and gameplay info has come out.

• The area is apparently much bigger than Outland
• There is an aerial gondola, a huge sea battle, and apparently an archeological expedition where you'll be able to fly planes
• All five Dragonflights appear in Dragonblight, a huge graveyard for dragons
• There's "a sister area to Un'goro," which means tropical rainforests. There are also lots of different areas within larger zones.
• Worgen and the sons of Arugal are back, and the Scarlet Crusade is now called the Scarlet Onslaught. And one quest is based on a mission from Warcraft III.
• Death Knight can turn dead teammates into ghouls -- "plenty of fun in the Arenas"
  
• There are "vehicle" quests, where players drive a vehicle (planes, trucks, or even dragons) around to accomplish tasks

Unfortunately, the Gamespy folks aren't raiders, so there's not much information about the new instances and raids in Northrend (in this piece anyway -- we've got more dungeons and raids info coming out). But just the mentions of some of this stuff -- the different vehicle quests (maybe Grand Theft Azeroth is realer than we thought) -- is enough to get us excited.

Many thanks to Tisen for tipping off the late night WoW Insider crew that Gamespy will be releasing new Wrath of the Lich King info in about an hour from now – at 12:01 a.m. PST. We'll get it reported to you as soon as we see it. Stay tuned for updates. Their entire announcement reads:

You're going to want to stay tuned until the midnight here on GameSpy.com. At 12:01AM PST we'll be flooding the site with all-new World of Warcraft: Wrath of the Lich King materials. New movies, media, a preview, a roundtable, two interviews and a look at the Death Knight. Enough for ya?

I have to admit, this is a little strange for it to be posted this late... but I've seen stranger things. More info as it comes in.

Update 12:05 a.m. PDT: No info yet. Though their website still says it's "Thursday." We're expecting something soon.

Update 12:07 a.m. PDT: Bornakk is up late and posted " They aren't the only ones..." in response to WotLK info being released tonight. More to come apparently.

Update 12:09 a.m. PDT: News is incoming, possibly from multiple sources, look for more posts soon.
