The "killed the family" route's been done twice in a row now. I think they'd pick a different angle.

On another note, it's Assassin's Creed III, if you mean the one after Brotherhood and Lost Legacy.

On ANOTHER note, I think that's more or less pointless anyway. They move forward in time to find where the Pieces of Eden went. Going back to Pharaoh Egypt seems pretty pointless storywise, too.
