NX is probably just an exit strategy for Nintendo to withdraw from the home console business. They release a powerful handheld system that perhaps has x86 architecture and also fits into a craddle where it draws more power and has fan cooling and creates better visuals for connection via hdmi. End result also a home console of sorts but not competitve with xbox or ps4.
Maybe NX is a VR headset that works with a lithium ion battery pack and again works better if you connect to mains. A light VR headset on the move that uses augmented reality so you still have outside vision of what is going on in the world and game graphics only take up part of the screen thereby reducing performance requirements and making it safer to use.
VR is so clearly the future but at what maturity does it get mass acceptance. I personally think the second generation will do it. VR is just so brilliant and amazing I don't think it will take long. It may be that Nintendo won't survive without getting into VR hardware.
