Well change the K1 for the X1.
Alright, but still, seems to be two or more pieces of hardware.
-handheld / portable (maybe more than one size, as usual)
-home console plugged into the wall
-perhaps an implementation of the SCD patent that can boosts the capabilities of the home console, or both console and handheld.
unified architecture, much easier for 1st party Nintendo teams to get games out that play on both main types of devices, even if console has some exclusive games.
Will be aimed at everything from the mobile market, to dedicated console players and even somewhat harder core gamers to whom graphics and framerates matter.
