World of Warcraft: Cataclysm is set to release on December 7, 2010 and will bring about slew of changes to the massively successful MMO like a new level cap, new areas, two new playable races (the Goblins and the Worgen), etc. Cataclysm will also introduce new dynamics to the current player talent tree.
