Regarding a more powerful Switch, you first have to consider : how much bigger they'd go, would it be ideal in handheld mode, and not betray the Switch's design concept? Looking at the 3 modes, 2 are portable, and IMO most optimized play options:
Switch OG
1. portable
2.dock
3. tabletop (6.2in is a bit too small)
So my first guess - a larger NS would be geared toward tabletop mode instead, & include a pro controller (instead of joycons+grip).
Switch XL (10 in.?)
1. tabletop
2. dock
3. portable - too big but not impossible
I definitely believe there's a market for a premium option. Might see a switch mini also, but starting to have doubts about a dock only solution, since the "Switch" concept has switching to docked mode as the secondary option by (its tech) design.
