What could the Switch2 'Gimmick' be?

My guess would be to use a folding screen. So in handheld mode it might have a 4x6 inch screen but then in tabletop mode you could fold it out to something like 6x8 inches. I'd imagine it'd be too expensive for a switch 2. But still it'd be a cool feature if it could be added.
