Virtual Boy's failure is one of the things that set VR back too.
Maybe a Virtual Switch would help repair things, though Nintendo said they've no interest in doing a metaverse, I can certainly imagine Nintendoland, Breath of the Wild and Metroid Prime with VR modes.
The thing about VR is that it's a bit like graphical upgrades: There are loads of experiences are enhanced by it, but very few are truly impossible without it—but once it's out, the vast majority of what's released for it isn't made backward-compatible with what came before. And in VR's case, the vast majority of
those fall into the middle ground where, yes, technically you could have released it as a non-VR title, but nobody would want it because it's so bare-bones that it needs the gimmick of 3D immersion to be worth anything at all.
And while, on one hand, if anyone can be trusted to release a VR experience that's not just a tech demo (especially now that the rest of the industry has already run that market into the ground), it's Nintendo... they're also the most likely to make a regular AAA game that could have worked equally well as a non-VR title but ended up being VR-exclusive anyway just because. And it's likely we'd end up with a repeat of the Wii where there was a mix of both.
But you mentioned
NintendoLand, and that reminded me how one of the (depressingly few) things Sony ended up doing with the first-generation PSVR was asymmetrical multiplayer, much like what
NintendoLand had except with a first-person camera.
The Playroom, I think they called it? There was also that one split-output game on PC that the Game Grumps played, where the one with the headset tries to pick out the other player from a crowd of wandering NPCs. And we know that Nintendo likes inventing new hardware setups that are also specifically geared toward supporting ports of older games. In the same way the Switch's Joy-Cons were made with gyros sophisticated enough to
almost emulate the Wii's motion controls (and the Wii Remote and Joy-Cons being able to double as NES and Super Nintendo pads, respectively), I could see them wanting to be able to bring back the WiiU's dual-screen mode for the Switch's successor. And the easiest way to do that would be to replace the dock with a wireless HDMI dongle like the Chromecast and Steam Link, so players can just hold the entire New Switch in their hands, screen and all, as they play a game on the TV. Or snap off the Joy-Cons and slide the screen into a headset dock... while still streaming a second feed to the TV so onlookers can see what the player is seeing... or what they
can't.
