But while that game promises to wrap up the story of Ezio and Altair, Ubisoft's already turned its attention to modern-day protagonist Desmond and his story. Which according to Revelations producer Alexandre Amacio will conclude before December 2012.

“In Assassin’s Creed we set up a timeline with this whole end of the world plot of December 2012,” Amacio said in an interview with Eurogamer. “That’s fast approaching, and the story we have to tell, we obviously need to do it before we arrive at that point.

“We had such a complex and strong narrative that we ourselves did our best to just try to execute these games before that date. It would be stupid of us to be centring a game on a semi-reality and then have that conclusion happen after that date in real life.”

That all but confirms an Assassin's Creed for next year then, presumably a numbered entry in the series. If we were betting people, we'd guess that the series would take a break after that before re-emerging on new consoles. But you never know. Assassin's Creed is a massive business for Ubisoft. It's hard to imagine a Christmas without a new game in the series at the moment.
