New game from Ubisoft?

But what game is it? Speculation!

Ubisoft is a sneaky company, and to be even sneakier they've sent out these three pictures that imitates posters from famous Hollywood-movies. Since they come from a games company, we are pretty sure it's supposed to tease a game, but which one? The date "September 14th" seems to be a clue to when we will find out more. Until then, these "posters" are quite fun to look at.
