If Rayman legends would have stayed a Wii U exclusive, would it have helped the Wii U as much as Pikmin 3 did?

I think it would have helped as much if not more, Rayman Origins sold more copies than Pikmin 2 so it has more fans.  But you also have to look at if the game is a system seller and the review scores are really high so I think it could have been.
