Good point. It's certain that the technology and market are changing rapidly at the moment. Didn't know about the 20 year deal, that would mean that a Tegra 2 or maybe a further development is almost a certainty.

If you see at what for example Apple is currently doing with it's M1 and M2 chips a lot is possible now that was never expected to be before.

A Switch is much larger and therefore much easier to cool than a smartphone. Therefore it doesn't really require an expensive, high-end smartphone chipset. The Nvidia Tegra is a different story and not really comparable to the modern Snapdragons.

I also believe Nintendo will switch to AMD for a cheaper, smaller chipset, but still actively cooled. They don't need to compete with Sony and Microsoft hardware wise, but the Switch definitely needs a jump in performance which should be doable cheaply that way. And a chipset like this will still be better and cheaper than a Snapdragon.

Fellow Switch user, but I'm just curious as to why you don't like the Switch controllers. If you're talking about the Joycons I can fully understand you, but the Switch Pro controller is really good in my opinion. Though it's not as good as my PS5 controller, I think it's just as comfortable to be honest. If you've never tried the Switch Pro controller give that a shot, saves you buying a console you might not even really use since you say you prefer Nintendo games.
