i was reading around and i read some rumors about how if you pre-ordered (digi download) cata - that you'll be able to see Deathwing remake the Azeroth ( like make the giant cut through barrens )
at blizzcon they said that servers would go down and then come 12am dec7 new azeroth will be alive.
I also read that this was the "suprize" that blizz had in store for us.
ir lookin for confirmation
