Although there is information being leaked about the upcoming expansion Wrath of the Lich King, because of the alpha testing that is currently underway, it is too soon to tell what will make it into the final copy, and what will not. Furthermore, most things will be changed, and there are details that may never be leaked until, of course, release.

Still, it is a valuable experience to peer into Blizzard's process of designing, reforming, and progressing the game's professions. This week, Insider Trader will focus on analyzing the tentative progression of the leatherworking trade.

In addition, we'll take a brief look at professions-related changes in the upcoming patch 2.4.3. While mounts at level 30 and Haris Pilton might be first in your mind, Blizzard isn't overlooking the trade sector this round.

First off, a Black War Elekk has been added in a recent PTR push! Rejoice PvPers, you now get a giant elephant mount. I know a few of my guild mates have been waiting for this, so I imagine it'll be a welcome addition, if a small one. I might get one for my Paladin, running around on the Charger is getting a bit boring and I honestly don't know what else would be appropriate.

For up and coming Alchemists, the Philosopher's Stone has been altered. Like the Alchemist's Stones after it, it is now a trinket. Also like the Alchemist's Stone, it'll do a little something for everyone. Emphasis on little. The new Philosopher's Stone will add 5 to each of the basic stats.

In addition to the little boost to Alchemy above, the materials for the new Alchemist's Stones have been toned down somewhat. Rather than 16 primals per stone, you'll need only six. That's anywhere from a 100 to a 300 gold reduction in price depending on the primal and your server's market, or a few hours of farming saved, so I really can't complain.
