There is no word of a delay, but there is no confirmation of a lack of delay, either.
We just recently got a bunch of marketing for the game, including standees, cover art, and the Playstation live displays just updated to include trailer and pictures of it. On top of that, the annoying as fuck TV is spouting the ad for it coming in September is playing every 10 minutes. There is absolutely nothing indicating a delay on our end. No news/execution changes. No date changes in our marketing kits.
Not to pop a bubble, but Gamestop employees would not know about this already. There was a rumor going around the district managers months ago that there might be a delay to November. That was before the official reveal of the release date.
I'm guessing that same rumor is resurfacing, OR, the Ultimate Collectors Edition is getting a November re-release, since Square confirmed they would be redoing and releasing more of them. Or, maybe it's a PC version coming in November, even though I highly doubt that..
Remember, we also listed PC as a pre-order platform for the game when it went up.
