Will the NX be compatible with all the controllers, from GC to WiiU?

[Darwinianevolution]

Nintendo has created a ton of controllers compatible with the Wii and WiiU: the Wii Remote, the remote+nunchuck, the Remote with the plus, the remote with the classic controller (and the GC that plugs with the remote), the original GameCube controller with the adaptor, the WiiU Gamepad, the WiiU Pro Controller, the Wii Balance Board... With the next Nintendo system, will Nintendo keep the compatibility with all those controllers?
