I know everyone's worried about the microphone being used for voice chatting with your random teammates lol, but I think nintendo gets that, I doubt it'll happen, so I REALLY hope we get some kind of voice chat implementation for splatoon or discord functionality, it would be SO convenient.
Right now if you want both the game audio and vc coming through your headphones you need a capture card hooked up to a PC monitor and it sounds like such a chore.
i guess the closest thing we have to 'official'/built-in VC is the NSO app's voice functions that nobody uses, so i could see that being directly implemented into the switch
as something you can only do if you're over a certain age (13, 16, 18, one of the three), you're in a room with folks on your friends list, and you specifically opt in. i'm very very anti-built-in-VC-in-splatoon but i'd be okay with that, especially since it already essentially exists with the NSO app
now, will it be good enough quality to make people who've already figured out discord switch over? guess we'll see, if this is even gonna be a thing and the microphone isn't just for blowing out the candles in tomodachi life for switch 2 (please)
