Accessory prices did rise though, extra controllers and such increased in price.
Pro Controller went from $80 to $85.
TIL Switch 1 controllers are compatible with the Switch 2, so it may not have that big of an impact.
I heard this too but apparently not to unlock the system or wake it.
But I’m happy I can keep using my third party controllers
Switch 1 controllers are class-compliant Bluetooth accessories as far as I'm aware. Same goes for a lot of old Wii/WiiU controllers which also still work on Switch and Switch 2.
