People are going to buy three or four attachments, use them for the five or six games that come out in a year on Nintendo consoles, and throw all the shit in the closet or behind the TV. People will reminisce about Mario and Zelda, then Nintendo will move onto another dumb gimmick.
Developers can barely give a shit about Kinect, PS move, VR, tons of other gimmicky attempts of shit, they're not going to design a game around peripherals you attach to a Nvidia shield.
This is pointless innovation for the sake of relevancy, but it won't sell well. Basically Nintendo's MO at this point.
