No one will buy the console variant. Why pay for another console, something that's less powerful than the PS4 when the portable Nintendo console runs the same games, like you said graphics are not a big differniator for cartoony games and Nintendo won't have to worry about realistic games because no Western third party will support NX in this case. They won't be able to port their PS4 engines easily to a system that can only run Wii U level graphics.
The portable variant will sell to the same audience the 3DS does which is decling, except now they won't have to buy two devices to play all the Nintendo games.
