So I've been catching up on my reading lately and I ran across this post at Random-Battle. Link
Honestly, I have been thinking this myself. Mainly because WotLK has been in development for a while. Will we see an early launch? I really hope so because I'm itching for new content and more zones to explore. Theortically the facts match and I would love to see the new talent builds come out with patch 2.4, that would all but confirm an expansion launch soon after. But to tell you the truth I am not going to get my hopes up, that gives me heartburn.
