If the NX handheld can come close to XBone levels of power (or at least can play XBone-like games in power) it will have some 3rd party, just by the fact japanese companies will love to put their JRPGs console games o handhelds, plus the Vita will not have a succesor: handheld monopoly. Western games are the big question here.
The home console will depend on the nature of what on Earth the NX actually is and how does if functions.
