I wouldn't rule out Nintendo prototyping an AR device somewhere. VR is too isolating, but AR is very user-friendly. It fits Nintendo well.
More specifically, the Apple's approach is perfect for Nintendo.
They can create a device that lets you play your Switch 1
&2 games on a large virtual screen (perhaps with stereoscopic 3D, hello 3DS games) and some experimental AR apps like Nintendo Labo without committing too much.
But if they create an AR device, they need a strong partnership with a major company that has some expertise in this field.
Google has reportedly killed it's AR project recently. Knowing those guys, there could be interesting and ready-to-use technology that are left on a shelf.
A bit a weird rumor, but not as far-fetched as it seems. At least, that's food for thought.
