I still do not see why this would be a prequel to Assassin's Creed IV in such a case. We did not have any such game with a number in it for previous titles so I don't see what you guys are basing this on.

I also don't know how it would be a prequel to anything. Only thing it could be is a prequel to a game with Haytham, and I think we can all figure that that's not going to happen, nor would it be a numbered title.
