The expansion--rumored to be dubbed "Cataclysm"--will add the Goblin race to the Horde side, with the Alliance gaining the werewolf-like Worgen race, according to the report. Blizzard has yet to announce a scrap of information related to the next World of Warcraft expansion. Any official word is likely to come at the company's BlizzCon convention, set to begin on August 21.

As a former Horde player, the prospect of facing an army of players affiliated with the Son of Arugal--that elite level 20 backstabbing son of a bitch--is certainly intimidating.
