I can think of a few things off the top of my head
Realistic Stuff I’d Like
Fitness Tech - I think there’s a lot of potential in fitness technology and Nintendo has some inter utilized properties in that field. Two relatively recent titles, Ring Fit Adventure and Switch Sports alone have sold about 25 million units. Considering a lot of the appeal of the Switch is that it’s a console for more active and fit people than Playstation and Xbox, I think this would be a good direction. Nintendo was serious about this a few years ago, and then went silent on developments.
More Scalability and Form Factors - I’m a big fan of more frequent hardware upgrades, so I wouldn’t mind something like Switch 2 Lite, Switch 2 TV, Switch 2i, etc… The OLED Switch was a nice upgrade, but they could have done better with a more powerful chipset. We’re also years into a tech period where RISC SOCs have different tiers - a major example is M2 base, Max, and Ultra - and software is compatible across all M-series chips. This is kind of a power thing, but it’s also a form factor thing.
True compatibility - enough with emulation modes, I want Switch 1 software to work the same as on all future Switch hardware, none of this “we’ll emulate it for a few years, you have to use your old controllers, then drop it altogether” bullshit. It’s 2023, and I’ve been sick of this for at least 20 years. If Nintendo does this, I’ll have absolute confidence in buying stuff from them - as of now, I’m done buying Switch games (aside from Suikoden) until they confirm this to be the case. The convenience in playing old software is a major thing for me.
Streaming/Capture Upgrade - I like the idea of recording my stuff to video. Switch has a half-assed version of this, I want the full ass!
TV and Cloud access - more of a software thing, but I want Netflix, Prime, Apple TV+, HBO, Disney+ and all that stuff accessible on Switch 2. Additionally, I’d love to have access to Dropbox and iCloud, at least from the docked station. If I’m doing media, I want to be able to get it directly to my editing software.
Voice Command Interface - simple: like Siri, Google, Alexa. When I’m searching for stuff in console mode, I don’t want to select characters with a D-pad or analog stick, touchscreens and voice commands are how this should be done.
Better navigation hardware - I’ve never used a PS5 (or was it 4) controller, but I like the idea of a trackpad on controllers. Also, bring back point and click like the Wii. These are features I think I’d like when navigating.
Unrealistic Stuff I’d Like
Basically, stuff I want, but I see good reasons why it probably shouldn’t happen:
AR/VR - is kind of out of the price range for a Nintendo console. I’d say leave that to Apple and Google. Unless Nintendo can figure out a way to make it feature competitive and a hell of a lot cheaper than the competition.
I describe myself as a little dose of toxic masculinity.
