Why are you assuming that Nintendo is stagnating in comparison? Yes, in the meantime new generations of other consoles have come out, but after equally long gap

Why are you assuming that Nintendo is stagnating in comparison? Yes, in the meantime new generations of other consoles have come out, but after equally long gaps on their side. (PS4->PS5 was 9 years, and Switch will outsell PS4 over its lifetime easily) And the Switch users I know generally don't care about PS5 graphics at all. It's not really the same market.
