They should just make the NX console upgradable in a modular easy to do way (much like the N64 Expansion Pak was). That way if XB2/PS5 comes out, they can release a more powerful NX then, and people who already bought the system could have the option of upgrading if they want and just continue forward that way.
Or do the whole supplemental hardware thing.
The supplemetal hardware is the way to upgrade the system with more power/functionalities.
Please excuse my bad English.
