While the new Azeroth was rolled out with a patch last month, the expansion pack won't actually launch until December 7. You can pre-order digitally direct from Blizzard now, but if you go retail you have the option of a $40 regular edition or $80 Collector's Edition.

As well as a revamped world, Cataclysm brings two new races--the wolven Worgen and cheeky Goblins--a higher level cap, more raids and dungeons, a new Archaeology secondary skill and buckets of other things you'd expect from an MMORPG expansion.
