Think Captain Toad might be he best shout here, as well as Splatoon. Especially if they manage to turn those into major franchises. Mario Maker will probably at least be fondly remembered as "remember that crazy time Nintendo let everyone make dumb levels?", or improved upon in sequels.
With the rest, I feel like a lot will be remembered as "good for its time", but not absolute classics. Things like Pikmin 3, Mario 3D World and Bayonetta 2 will be fondly remembered but they were kinda of iterating on previous successes and didn't raise the bar for their genres in ways that Mario 64 or Galaxy did.
Ditto for the RPGs on the system, they'll probably be seen as good games, but not Final Fantasy 7/Chrono Trigger-level revelations.
Likewise, Affordable Space Adventures, ZombiU, and both Star Fox games will probably at least be seen as "innovative with the controller", but I'm not sure they'll be trendsetters.
Wii U has an embarrasment of riches when it comes to sidescrolling platformers with Yoshi, DK, Kirby, New Mario/Luigi Bros, Rayman Legends, etc. but while Rayman and DK both did cool new things I'm not confident they have rewritten the playbook for all platformers to come. Rather they were just excellent executions of their genre.
