I don't know. I mean I hear you, but as a long time Nintendo fan I honestly think their future is mobile. The chances of Nintendo having another Wii-like success on their hands is slim to none in my opinion. The simple fact is that their software would make an absolute killing on mobile and the casual audience will always be there. No need to worry about selling hardware to the masses when they have a direct line to the casual market through phones and tablets.
Furthermore, Nintendo would be great as far as helping mobile gaming evolve and quite possibly give something like the Apple TV a shot in the ass on the gaming side that it needs to make it something that should be taken seriously. Heck, imagining their VC library on the Apple TV with a Nintendo branded MFi controller gets me cised.
It's clear they won't be going mobile-only anytime soon, if ever, but it's becoming harder and harder to justify buying Nintendo hardware when we have plenty of devices that are more than ready to become the perfect home for their games.
