Well, it's official. The World of Warcraft expansion, the Burning Crusade.

From what blizzard told us now, there will be a lot of fun things. Blood Elves, we could've seen comming given the enormous amounts of requests. I am very much interested in the socketed items and the new profession; Jewelcrafting.
Probably it will create trinkets and items to be socketed.

Anything I forgot to mention? Ooh yes, Outland. And the time traveling. I am wondering how that will work out?
