oh realllly. With episode 1 they announced in late june that it would be july 10th. Im sure they wont miss out on another opportunity to hype the date in advance, once they know it.
edit: plus, im betting whenever episode 2 is done itl need a check mark from activision. So that in itself is probably a week of waiting. So once its ready, thats probably when they talk dates, and get it approved and finalized in the meantime.
