The actual games don't need any voice chat when playing with randoms but there should be a party chat for when your playing with friends or in game chat when you private squad, Even on PS4/X1 random matchmaking people never even use microphones anymore and if they do its usually just someone who left there mic open with music playing or screaming kids in the background you have to take the hassle of muting.
I see no reason to why the NX won't have party chat and I fully expect it to.
