Emile Gauthier of Ubisoft has tweeted that the company is working on a MMORPG. What's interesting though is that job listings linked to by Gauthier suggests that this title is in development for the Wii U. That doesn't mean it'd necessarily be an exclusive, but even as a multi-platform title this'd be interesting. There's also mention of the game being a AAA title, meaning it could end up being from one of their bigger franchises like Assassin's Creed
