The 3 pillars would be: ¹better motion controls for the joy-con, making it a 6DoF controller; ²body tracking much ahead of anything microsoft's kinect could do; ³a lightweight and cheap - but high quality - VR headset that would launch 2 or 3 years after the console's launch.
So, for the first two we would basically need cameras. Personally I would put cameras on the tablet itself (I would sacrifice the up bezels making it a bit larger to accommodate the cameras as I believe it would be a great trade-off, and would enable this experience on tabletop mode too.
With an add-on accessory (that would come in the box) you could transform the joy-con on a
VR like controller, with sub-millimeter accuracy. It would have that traditional ring shape (from VR controllers) with the IR LED's to be tracked by the cameras. The same cameras would be used to perform the body tracking (it could even do both trackings at the same time, like it's done on meta quest 3)
It would be something like this (it's just an example, don't mind on the quality of the execution here)
Also, Nvidia has a model for body tracking.
All these machine learning algorithms would be running on the Tensor Cores.
About VR, I made this post the other day:
Or they could just use the tablet (that millions will already have) as the computer unit.
This is an AR device called Magic Leap:
Just replace that compute unit with the switch 2 tablet:
Yeah, not as clean as a meta quest, I know lol
But hey! Apple is also using cables! (to connect the HMD to a battery lol)
This would be much cheaper, and the VR device wouldn't compete for components (manufacturing wise) with the hybrid console.
This approach could offer cheap VR (for those who already have a Switch 2, and I'm thinking something between $150-$199) in a very lightweight/comfortable headset that would only contain the 2 lenses, 2 speakers, one or two screens (it's up to them to decide which approach is the best from a price and weight perspective), one IMU, and 4 cameras. Pancake lenses (which enables both the clearest visuals and a slimmer design) are a bit expensive now, but it would get cheaper in 2026/27 (when I would expect Nintendo launching the headset). Although a cheap solution, it would still offer a high quality VR experience.
And, of course, we don't need controllers to be bundled with the HMD because every Switch 2 owner would already have VR ready controllers. Make a Mario Kart for launch and Nintendo would steal a lot of Meta's customers...
I believe that if they did all this, it would greatly expand on how versatile a hardware like the Switch can be. They would be crazy not to do this IMHO
BUT... it's Nintendo, so...
Kidding...
Sometimes it really appears to be the perfect idea on our minds, but in reality it's just a very subjective take, and most people would not bother lol
Anyway, I'm so convinced that this would make the Switch 2 to sell at least as many units as the Switch that I'm definitely setting myself up for disappointment... and that will be on me.
