Its been confirmed by a Blizzard Poster (Blue) on the WoW forums that today during the maintenance that Patch 2.4 will be patched in. Yeah.
Get ready for lots of lag in the new zone, broken addons and UI's, more dailys to grind as if 20 wasn't enough. New faction reps to grind as well as Badges of Justice to grind and Pugs from hell with the new 5 man Instance/Heroics as well and all the other good stuff.
Cheers its about time. Still need 31 Badges to get my new Badge legplates. I better get cracking.
