[quote]Is it going to be 'Journey' style were you don't even know the name of the person you are playing with?[/quote] No way, hombre. Bungie is going full social on this game. You'll know more than you'll want about your playmates. Co-op is supposed to be at around six players. At least that's the last I've heard of it. Competitive will probably be larger-scale battles between the factions, kind of like what AreaNet did with Guild Wars 2 and its World vs World. But how could they leave out the smaller scale 6v6 matches we all loved in Halo? They'll throw something like that in, no doubt.
