> There are significantly more sales of PS4 than switch

With a 4 year head start, the PS4 has 116.9m, the Switch has 103.5m[1]. Averaged over the years, the PS4 is lagging the Switch by nearly half - 14.6m/y vs 25.9m/y, no?

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.

PS4: ~117M sold in 9 years Switch: ~104M sold in 5 years

Switch is averaging 20M units/year and PS4 is averaging 13M units/year.

PS4 has sold 117m units (around 1m in the past year) and Switch has sold 104m so far (around 20m in the past year). You can bet Switch will overtake it very soon...
