Your average joe gamer isn't here on this site every second of their waking day just gagging for news either. If people want the game they will get it regardless of whatever leaks out.Yes, me too, but I'm a racing nut, but for your average Joe Gamer who isn't a big GT fan, in a few weeks the hype will be gone for these people, who are probably the biggest market for Sony.
When gameplay videos start appearing, it's basically like the game is out, which it kind of is, so holding off for a big launch party type thing makes no sense, if the games are in the shops stockrooms get them on the shelves......
