Will NX be backwards compatible?

[Maraccuda]

The thing with Nintendo and backwards compatibility is that they have moved themselves into a corner.
No doubt the NX will have some new way to play, but to play past games you will need a specific controller.

So imagine a Nintendo console 3 gens from now. Will be digital and fully backwards compatible, but need controller for NX games, gamepad for Wii U, Wiimote for Wii games, etc.

I like backwards compatibility but it is becoming counterproductive on Nintendos part.
