Blizzard announced their latest World of Warcraft expansion, Cataclysm today at Blizzcon. Two new races, Goblins and Worgen will be joining the Horde and Alliance, respectively and both factions will receive new combinations of races and classes. They’ll also be raising the level cap to 85, adding flying mounts to all of Azeroth, and altering the terrain of the whole of Azeroth (some real bad stuff is going down). Interestingly, a new guild leveling system will be implemented (I’m not sure how that will work, but it sounds cool). Oh, and there will be a new secondary profession, Archaeology, enabling players to finally realize their in-game archaeological dreams.
