Is the NDA so strict that someone couldn't tell me if there is in-game chatter from your own character during multiplayer based on your environment?

EDIT: I ask because there was in the first Bad Company, but not in the second, and I happen to know someone who was pretty disappointed when the second game didn't have it. Stuff like your character yelling "Grenade!" when one was thrown near you, yelling for a medic when injured, etc.

Origin is great. I wish Valve would copy it.
