Until very recently, it was a cardinal rule of the gaming industry to not place multiplayer in a game as DLC content, since it may not work very well once added, (just look at Dead Space 2's multiplayer' ugh...). I'm thinking since this is co-op only MP, it will be stndard with the disc once released.
