Actually, it would probably be easier for Treyarch to make a Wii U game, because they can port over the entire game and engine as-is instead of modifying it. All Treyarch would really need to do is program the second screen and all the other gizmos in the Wii U controller. They may also improve the Wii Remote interaction, as the Wii U also uses Wii remotes.
