We could almost use a NX speculation thread.
The most info we have on it are an alleged leak of the controller online (really funky, btw) as well as connections between the latest delay in BoW and the NX release.
Nintendo delayed BoW to investigate "new possibilities" for the game. Because it will be released for the NX, this could mean they delayed it to both "improve the quality" of BoW as well as possibly implement new tech for the game in accordance with the NX's hardware, just as TP got some fancy new motion enhancements for the Wii release (sword swinging and pointing the remote, to be specific... ??.)
Due to the latest craze in VR and Nintendo's proclivities for new trends (see: gimmicks,) I believe they'll be looking into this for BoW. But it 'is' Nintendo. We've been surprised before.
Still... touch screens, motion control, body recognition, 3D... Every trend that's hit the market has been at least taste-tested by these guys. And they haven't touched VR yet.
Edit:
I know what you're thinking. The Virtual Boy does 'not' count.
