I think Nintendo will push Switch hardware as long as economically viable. Which means they can delay a Switch successor to even Q4 2025 or even Q1 2026.
Which would mean 175 to 80 million might not be outside the scope of possibilities. After BOTW 2 Nintendo can focus in developibg Switch 2 is library and repeat the succes story right out of the gate with a massive lineup in the launch year of Switch 2.
