Can you please put me down for 2012? My bold guess is that the NX will be a 3 device code name:
1) Wii U - Rebranded NX 1 and sold for a lot less (minues the gamepad). Already released, but will do a rebranded in the future.
2) NXP (Portable) - Same hardware capabilities as the NX 1, but portable. Handheld with 1080p screen(s).
3) SNX (Super NX) - 4k ultra game console device
I suspect I'm the only one that is predicting we already own part of NX (and have since 2012).
