The Daily Grind: Is "Cataclysm" the name of Blizzard's next MMO?

Yesterday, the news first broke that Blizzard had applied for a trademark on the name "Cataclysm", in the fields of computer games, paper-based products, and online entertainment services, according to an article at Speculation has spread across the blog-o-sphere as to what this new trademark could be. Could it be the next WoW expansion? More likely it's the name of their next-gen MMO they're said to be working on.

But what if it's not? As the article points out, StarCraft: Ghost was also trademarked, and it never actually materialized. Is this Blizzard trying to throw us a curve ball, or is it really a solid lead into what could be Blizzard's second go at a successful MMO? Of course it's all speculation at this point, but from the information presented, do you think Cataclysm is the next Blizzard MMO?
