Nintendo NX: 10 Wishlist Rumours That Must Come True

7. A Customisable Controller Interface

Different to the idea of a fully morphing controller that doubles as a screen, Redditor stimpak_vendor has proclaimed to not only be a AAA developer with access to Nintendo's prototype machine, but then went on to detail how the controller is fully customisable.

They state:

"The screen on the controller doesn't show the gameplay like the Wii U gamepad's screen. Think of it as a skin that you can customize, and put icons behind the buttons, and also a touch interface so you can add more actions to the controller. There is a way to stream the main gameplay to the controller, but that's not the main feature of it having a touchscreen [...] The screen is the whole controller."

If true, it would appear the form factor/shape of the controller and its buttons are set, but 'behind' said buttons (as the controller is essentially one large screen) you can customise what does what. The nearest comparison I can think of comes from Monster Hunter on 3DS, where in the game's options, you can dictate what panels sit where on the bottom screen, thereby giving yourself access to whatever shortcuts you most frequently use.
