I'm guessing it'll be "delayed," just a guess though.
And you can't really call it "delayed" because this is GameStop...they and all other retailers usually make up dates before the official announcement.
It may very well be that insiders in retail know that the date is September 4, but it's not official, so if Sony decides to make it late September, it's not really a delay if that's the first official date they give.

Bet with disolitude: Left4Dead will have a higher Metacritic rating than Project Origin, 3 months after the second game's release. (hasn't been 3 months but it looks like I won :-p )
