Ubi at work

What could Ubisoft be thinking regarding the Assassin's Creed III timeline? I suppose there might be two or three possibilities here - somewhere between AC and ACII (around the14th century), or maybe the French Revolution(18th century)? Now, what could be the third? Is there a third option, anyway? If I were Ubi, I would ask artists and writers to show some work in all the possible eras and choose what I like.
