Any Mario Sports variant is extremely likely, because those have happened on every platform since the N64. Luigi's Mansion U is a possibility after that game's success on the 3DS and Next Level Games being a Nintendo exclusive developer since January 2014. I also think it's pretty safe to say we'll see another Punch Out game on the Wii U after its success on the Wii and Little Mac's inclusion in Smash Bros.
