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.
6. The WoW Insider Show discusses 10-manning Arthas.

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.

Like the Dragonblight, we've learned a little more about the Grizzly Hills in the last few days. A few old friends make a comeback in this zone, and I'm willing to say here and now that it's going to be awesome. Read on to see what we know!

• The Grizzly Hills will be a low to mid 70s zone. The setting is very much like a redwood forest, Warcraftified.
• Home of the Grizzlemaw Furbolgs, one of the largest furbolg tribes in Azeroth. The furbolgs seem to be under attack on a few fronts. The first front being...
• The Venture Co. This organization, founded by a bunch of jerk goblins, is working endlessly to clearcut the great Grizzly Hills forest. Second, the furbolgs are also having trouble with...
• Corruption from the Old Gods. Or maybe just one Old God, we're not sure. I would be willing to guess this is the Old God in Azjol-Nerub.

The WoTLK Bestiary has been updated today with the next monster in the series: the Iron Dwarf. These fearsome creatures, uncovered by the Dwarven Explorer's League in the Howling Fjord, are apparently a missing link between the Earthen and the Dwarves, an Iron-skinned race with runes of power etched on their skin. Unfortunately, they appear to be nearly as surly and destructive as the Troggs, not only fighting against the Explorer's League, but outright destroying any artifacts that the Explorer's League could find useful.

There's not too much info on them yet, only a few paragraphs and a sketch, but it's certainly exciting to see a new chapter in the storyline of the Dwarves. The Iron Dwarves look like they may be the next step in the storyline that began at Uldaman, another piece of the puzzle of the Titans, so that could have reprecussions for all races, and give us more insight into the origin of Azeroth itself. Perhaps we'll encounter more of them at Ulduar, or at the ancient Dwarven citadel of Thor Modan, or find out that they have their own copy of the Plates of Uldum or other such historical artifacts.
