Given that I think there's some legitimate hype/interest for Xenoblade, and that it's a more "hardcore" type of game, I would guess it would have the highest first week sales because I think it'll be the most front-loaded. Most of the others will have legs and so the first week sales won't matter as much. Xenoblade, however, will follow the more typical sales pattern you see from most games on Playstation and Xbox.
