Blizzard has finally let the cat out of the bag. The latest World of Warcraft expansion - Cataclysm - will be released on December 7th.

"Cataclysm includes the best content we've ever created for World of Warcraft. It’s not just an expansion but a re-creation of much of the original Azeroth, complete with epic new high-level adventures for current players and a redesigned leveling experience for those just starting out," said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. "With the help of our beta testers we're putting on the final polish, and we look forward to welcoming gamers around the world to enjoy it in just a couple of months."

Cataclysm will be available in regular retail, collector's edition and digital download versions.
