According to Ubi this will be the final chapter in the Desmond trilogy so I don't see how they could justify another game after AC3. I also think that this was Ubi's way of giving the fans the different elements that they so desired, by that I mean the colonists and international factions involved (i.e. French. English, Dutch. Native Americans etc).
