Original: Acclaimed developer Blizzard Entertainment (World of Warcraft, Diablo, StarCraft) has filed new game-related trademarks for "Cataclysm," and that's all we know.
The studio is known to have at least four projects in development--World of Warcraft, Diablo III, StarCraft II and a new MMO--with the company recently confirming that the new MMO is to be the start of "a brand new franchise" created "entirely from scratch." In addition, rumors of a fifth mystery project began circulating earlier this year.
As one would expect, the filings have triggered a tidal wave of internet speculation. Some believe "Cataclysm" to be the name of the next World of Warcraft expansion, while others suggest it could be the new MMO or a new branding for the redesigned Battle.net.
