some people say its reaching its saturation point... but switch is starting to gain traction in markets nintendo was never strong in, like the rest of asia , china, and europe, that PS pretty much already had in thier portfolio since the PS2.in these markets the switch officially launched around 1 to 2 years late... which can be the difference maker here.
especially in places like china where its heavy on censorship, nintendo being mostly first party is a pretty big advantage.
