While we are hopefully running it 3v3 or 4v4 the decision is ultimately going to come down to how many copies of the game, 360s, and tvs we have. I hate to put it off like that but that’s how it seems to be going at the moment.
Teams would be randomized, by the way. So there is a chance you’d be together but no guarantee. 
Edit:
Here is the thread for Halo3/CoD4 settings if you want to drop in and leave some feedback!
