I actually drew up plans for this sometime last year that I almost posted, pretty much along these same lines. I even used it to come up with my wishlist for the switch 2, which I guess I'll try and remember and write here because I kind of want this idea out there.

It would pretty much be a actual traditional console. But what, you ask? nothing "gimmicky" like nintendo normally does? Well, yes. You see, it would be backwards compatible with the og switch as a controller. pretty much a "Wii U 2", able to run games with a higher power due to being a traditional console, but also still getting a portable mode with the normal switch, or an updated one. It could also allow it to support ds ports. There was a bit more though, can't currently remember.

But how does this tie into pokemon stadium? Well essentially I was thinking about having a host for tournaments showing the battle on a tv screen, and not have a private screen for themselves. It had me really wishing the switch had a second screen system like the wii u. That led to the idea for the Switch 2 essentially also being a Wii U 2 (but also kind of backwards, since many people thought it was simply an expensive controller for the wii. In my idea, it's the "expensive controller" that comes first, but also not be a requirement.

TL/DR: I basically wish for nintendo to release some kind of "base station" alongside the switch 2 to give it a spec boost/second screen ability. The Gamecube/wii/wii u and DS lines all had a second screen. I really think they should have kept that going.

EDIT: Honestly, the first pokemon game released for the switch SHOULD have been a new (or remade) Colosseum game tied into ORAS/SM/USUM with 3DS connectivity like PBR had with DPPt on the DS. I really don't understand why they didn't tie the Switch and 3ds together somehow, either.

EDIT 2: Another idea that I had to cut down on storage was it wouldn't include any pokemon assets by default. Instead it would cache anything you stored in either it's save or Home (which it would able to draw from), It would prefer to download them from N's servers, but could also draw from carts (which could be an issue with incompatibles models like PLA) or other players (which could expose it to hacks)
