Majority of Nintendo games are on the PC anyway. :P Just through less than ideal means. (Legalities of which vary from region to region, thus by extension your mileage may vary.)
In Glorious 1440P-1600P-4k no-less!
I would love to see it happen, doubt it will.
I think if Nintendo were ever to exit the hardware business, they would probably become mobile developers for iOS/Android/Windows Phone as that's more where their targeted audience tends to reside.
