Nintendo has said precious little about its plans for the NX (other than that it won't be like a Wii U), but it might have hinted at what's coming through some recent paperwork. The console maker has filed for a patent on a gamepad design where a touchscreen would cover the entire front panel. You'd still have familiar elements like analog sticks (poking through the display) and shoulder buttons, but the usual front-facing buttons would be replaced by context-aware touch. The move would give you the adaptability of a smartphone interface with the primary controls you're used to in a TV system -- you could even use the controller on its side, or get visual effects when you press buttons. It wouldn't require a gigantic body like the Wii U's gamepad, either, and a card slot could take game data directly.
