I'm posting this to clear up confusion and maybe mmo-champ should put something up on the home page somewhere if they have the chance, but Cata goes live December 7th, PST. This means exactly what most of you think it means, You will be able to play Cata at 12:01 PST, or 3:01 EST. It does not matter where you are in the world or when you get the game, it all revolves around Blizzard doin their thing in Cali. So people please stop saying things like "The east coast will be able to play 3 hours before the west coast! whoo hoo!" This has been confirmed by Blizzard and blue postage.
p.s. this is not a rage post but rather some helpful info to clear up the confusion.
<Moderator Edit: This poster is WRONG. He is correct for US but completely and utterly WRONG for EU. Cataclysm is launched at 12:01 CET in EU>
