What could the Switch2 'Gimmick' be?

It wouldn't surprise me if the asymmetrical gameplay idea happens; the ability to interact with Switch in many ways would be great. I would prefer if the unit was just a solid body design this time though with nice sticks/buttons and better ergonomics, able to sync existing joycons to it for table-top play or whatever.

But as far as guessing new additions I'll go with clickable scroll wheels added to the controls.

Clickable scroll wheels I can see. What kind of game applications could you imagine? I'm thinking perhaps a rhythm game where you can use the scroll wheels to match the pitch.
