When Nintendo first unveiled the Switch 2 last month, we (and everyone else) noticed something peculiar about the new Joy-Con controllers. Now, some recently unearthed patent filings more or less confirm all the theories.

Newly-published Nintendo patents show that the company has been exploring a version of its Joy-Con controllers that can work like a computer mouse, a feature Nintendo has hinted will be coming to the Switch 2.

This confirms what many fans suspected upon seeing the Joy-Con controllers sliding around a surface on their sides during the announcement trailer last month. Presumably, the “mouse operation” feature will allow some games on Switch 2 to be played with either traditional controller inputs or mouse inputs.
