At BlizzCon 2009, Blizzard Entertainment has officially announced World of WarCraft: Cataclysm, the next expansion pack coming to World of WarCraft. The rumors were spot on with the level cap being raised to 85 and Kalimdor and the Eastern Kingdoms will be changed by the events in the story of the expansion.
As rumored, the Goblins will become a playable race for the Horde and the Worgen will go playable for the Alliance. New dungeons and raids will be opened up and some older encounters like Onyxia's Lair will be updated.
Cataclysm will use the phasing technology that debuted in The Wrath of the Lich King to "literally change the face" of Azeroth.
Expect more details as BlizzCon 2009 continues through tomorrow night.
