This is just a completely off the wall idea that has very little thought put into it.
Anyway heres the crazy idea Nintendo goes thrid party develops games for Playsation, Xbox, PC and tablets/phones for ~5 years then stops and releases their own hardware, which all Nintendo games become exclusive to again. So it would be 5 years of advertising essentially or a way to poach gamers from other platforms.
Edit: The better option would be to release demo's on the PC to advertise their games.
