Nintendo unsure if Splatoon will have voice chat.

[Gammalad]

Honestly I think the chat in Splatoon will be a lot more civil than COD if it does, and no doubt will, have voice chat. I think that there will be open lobby chat for people to smack talk and what not, and then it will be team speak for the remainder of the round. In a game like this communication is key. I can't tell on the map alone if my friends need back up or if I should be on the look out for enemy players that managed to surf by undetected.
