Blizzard has been working on a secret MMO for some time now and details have been ridiculously scarce ever since the project began. However, if a recent trademark filing is anything to go by we might be one step closer to discovering what the game’s title will be.

Cataclysm is the filing and was filed for use in the field of online games, computer games and paper based products. There’s no telling if this is actually the MMO’s title but those 3 fields look pretty convincing considering the MMO would be an online computre game and most likely have some sort of trading card game like World of Warcraft.
