Nintendo has said very little about the upcoming NX console, but a patent filing may give us some clue as to how it will be controlled.
The console maker has filed a patent for a gamepad that has a touchscreen covering the entire front panel. The controller will seemingly still feature analog sticks and shoulder buttons, but all face buttons will be replaced by touch controls.
Meanwhile, the Wall Street Journal reports that the NX will include a "mobile unit" that could be used separately from the main console. This patented controller features a card slot, meaning that you could use it without being reliant on a console and TV setup.
Of course, this is just an application, so there's no guarantee that this is the approach that Nintendo will take. But this is a company that is willing to try new things and embraced the idea of playing console games on a controller when the TV is in use, so perhaps this is a direction that it's willing to explore.
