I'm actually looking forward to a WoW expansion for once... Maybe now we'll have the info necessary for me to flesh out a Pandaren race. Always thought they'd make the perfect custom race (along with Naga and Goblins... Oh, and of course Jungle Trolls. :P)
Also, while I've never played Diablo, I must say that trailer was... well, creepily- awexome. I mean, for the first time, I felt like I was looking at a real person (the close-up of the girl in the beginning). Is it just me, or are we in the future?
