I never said the Switch Hardware would drop off due to their existing IPs already being on the platform, I said new games will do little do boost hardware. The Switch hardware dropping off is projected from other Nintendo hardware. Of course impossible to know exactly how the Switch will age but as time but what is the argument against a Switch 2 offsetting this (outside of, they can continue to sell Switch 1) because they can actually just do both. All the meanwhile benefitting from software which you complained about being missing a few months back.
Again, there's a reason what you suggest hasn't been done to other successful systems in their 4th year. It's simply a bad idea. You'd be missing out on millions of potential Switch sales by replacing it prematurely, and millions of lost sales translate to hundreds of millions in lost income.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
