World of Warcraft at Ten Ton Hammer

Blizzard Community Manager Zarhym didn't reveal anything unexpected in a response to recent questions on the official WoW forums but reiterated what we've been told. Blizzard's next MMO product will be a brand new IP, meaning sorry Diablo and Starcraft fans, maybe next time.

We have nothing to advertise for the new MMO because it’s a shell of a game thus far. We’ve already stated it’ll be a brand new franchise, which means the lore, art, and game play are being developed entirely from scratch. It’s an overwhelming process, but a process through which we excel. Our track record supports this.

Read plenty more about it on the official forums.
