"Feature parity with Halo 3" means exactly that.
That means 4 player campaign coop over Live, up to 2 players per box. Firefight also is 4 player coop over Live, 2 players per box. You'll notice this is identical to Halo 3.
Not sure why you think otherwise, but whoever told you otherwise is misinformed.
well since your here would you mind answering me this question? say you are playin with 3 other people and one of them triggers a flashback, does everyone go into the flashback even if one person is all the way on the other side of the map?
