Nintendo has been granted a patent for a game controller with a unique free-form touchscreen built into it, adding fuel to ongoing speculation that the new system the Japanese company plans to unveil in 2016 will be a hybrid console and handheld. The patent , filed in June and published this week, shows a flat handheld controller with a screen that curves around the edges and wraps around two thumbsticks on either end, resulting in a touchscreen that covers the entire face of the device.
