I saw a post by the mod "Mithan"? at the WoW Vault forums stating that Blizzard had stated themselves. The servers will be up and ready for play at 12:01 AM PST on the 23rd.
It's a good thing too, because I've become addicted to this strange little game called Alchemy here.

While going through the WoW withdrawls. It's rather challenging for a simple little game. I spent most of last night into way early morning playing that game and I'm at it again right now lol.
The best I could do was to clear 2 boards and get quite a way into the third before I got stuck and couldn't go any further.
Most of the time I can't even clear the first board though lol. Come on WoW!!!
