I think Nintendo's best bet is just to lock up a deal for sports games.
For EA, get Madden NFL, FIFA, PGA Golf, and NHL guaranteed for 5 years. Ditto with Take2 and NBA2K.
Offer to pay half the development cost, and program in a "Mario Sports" mode in each game as a bonus arcadey mode (so you have "Mario Soccer" if you get FIFA).
And that's about it. I don't think they're really going to get the big, huge PS4/XB1 adventure-action games. It's going to be too much of a pain in the ass to port.
Just have the sports games, those should be technically doable without too much fuss and it offers some depth to your library beyond just Mario & Friends games.
