Nintendo’s recent innovation hints at upgraded controllers for Switch 1. If that happens, the old console could stick around for another eight years.

Nintendo gave gamers a sneak peek at the Switch 2, but little else. Here's what the teaser video confirmed, plus the rumors still swirling around the upcoming console.

A machine translation of the full text of the patent describes the controller as "a novel input device that can be used as a mouse and other than a mouse." In mouse mode, as described in the patent, the user cradles the outer edge of the controller with their palm and places the inner edge "on, for example, a desk or the like."
