With that said I completely see where you're coming from and think that their games in particular match a lot of the ethos of Apple's own products. I do wonder if the internal cultures are vastly different though? The Bay and Japan have very different approaches to problem solving and business in general.
It just feels to me Nintendo doesn't have many options. Other than the IP, people would rather use the Steam Deck over the Switch. This was also a similar hardware story for non-mobile consoles.
Meanwhile, both the Switch and Deck are roughly an iPad with dedicated controllers. And the future is VR, but Nintendo is struggling with frame-rates even on the Switch.
I can see Apple making a deal with Nintendo, to build its next console as a peripheral on-top-of the iPad / visionOS. All the power of Apple Silicon and all of the inspiration of Nintendo IP.
They're not going anywhere, nobody's going to buy them.
This is very tech people loop take. Targeted people just want to play games.
