Has anyone played Halo 4?

In all original Halos (except the first), allied NPC's will often say funny things when you walk up to them and look at them for a few seconds. Do they do the same thing in Halo 4? I only wonder because I haven't been able to get the game yet and the npc ally's funny sayings are a big part of Halo for me.

Also, even in the first Halo, npc's (both allied and enemy) have been refined to the point where they even say things if they accidentally hit each other. It's even to the point where the player's allies have lines in the case of accidentally killing the player.

Has anyone played Halo 4 and payed attention to the AI to answer these pointless questions for me?
