Halo 3's Campaign was about 5-6 hours worth (in my playthroughs of the game). Who's to say that ODST's individual missions can't be as long (or even longer) than Halo 3's mission. We can't make a fair judgement (regarding Campaign length) until we actually have the game. We do know, however, that the open world envornment can mean massive replay value.
