Commercial reasons? There's no reason for them to pander more heavily to the American market; AC already tops the charts in the US. They could have made it in pre-contact Easter Island and it still would have sold superbly.
True, but I think this will work well in getting new fans on board.

Regardless, I think we will see Revolutionary France. Revolutionary America precedes France chronologically, and the French are certain to be heavily involved in the plotline. Since Enzio's story was covered over three games, it makes sense that this next fellow will also get multiple games for his story. It would make perfect sense for the protagonist to move to Revolutionary Paris in a follow-up game.
Good points.

Well, he'd basically just be Spiderman with a shank.
