I don't know...Sony tried to screw Nintendo then (asking for majority of royalties from Nintendo IPs on that system), and Nintendo screwed Sony (Didn't say it wasn't happening and went with Phillips instead) so there's a lot of bad blood and something is bound to happen again.
Hell, look at what happened between Nintendo and EA. They had a great partnership building. Battlefield was to be a Wii U game, with major focus on it, among others...then it collapsed. Nobody knows why but the general consensus through insiders is that EA wanted Nintendo to be solely on Origin, putting EA in control, and Nintendo rightly told them no.
