What elements of next gen could the Switch's successor implement?

I think 4K resolution (docked mode) for certain games and video streaming is the best we can hope for. Ray-tracing, 3D Audio, and the really complex AI possibilities are almost completely out of the question if Nintendo wants to balance battery power, cooling, and pricing.

Basically think of a PS4 Pro. That's about the best I can see Switch 2 performing docked, maybe slightly better or worse. It won't be as capable as the Xbox One X, and nowhere near the level of the Xbox Series X and PS5.
As for the controller, it doesn't need triggers on the level of the DualSense. But how about analog triggers again (absent since GameCube), a headphone jack, and speaker/mic.

I dont think its reasonable to expect a Switch 2 to be close to a PS4pro (straight 1440-1800p, and a few 2160p games).
Its too power hungry to get down to 25wattage range of the Switch. 

I could see maybe 1080p + DLSS to upscale to 1800p-2160p (4k) in certain games.
That might be possible with a newer switch when docked.

Ray-tracing is extremely demanding for what visual improvements it brings.
So its probably not something you want to focus on, with a system that is already constrained.
Ei. its wastefull (for a smaller system), so unlikely to be used.
