Switch 2 Joycon Leaks; New Mouse Capability?

It definitely looks like the same thing in the Lenovo Legion Go which has the detachable controller usable as a mouse .

Also the shipment parts leaks apparently have listings for "mouse sole" for the Joycon, yeah think a mouse functionality is happening:


Also this one is NOT REAL, just a fun mock-up of what the box could look like with the orange/blue + matte black console color scheme and new rounded dock design
