Dont be shocked it when the NX internals are brand new tech. ps4 and xb1 i always felt were half cycles based on old pc, which they are. but when you look at n64/ps1, gc/ps2/xb, ps3/wii/xb all those systems were based on brand new technology. Yes, even the wii because it implemented a lot of the same concepts as todays VR.
Rumor has it that the NX can be taken with you so it wont force you to play on the tv, but be careful what you wish for because it sounds like the makings of a game that can never live up to high expectations.
