Confirmation of Season Pass. I would bitch and complain and maybe even buy used as I did with a couple of previous Battlefield games (not 4, avoided it altogether) but since it launches with 15 maps I think that is enough content to justify DLC talk already. Not that they require my approval, just my personal opinion.
