What would a Sonic game made by Nintendo be like?

So if Sega lets Nintendo make the next big Sonic game after one comes out for PS4/XB1 how would it turn out? I think it would a 2D platformer (which Sonic needs more of, and we know how much Nintendo loves dem 2D games) But it would on the same level of TF in level design and gameplay
