Reasons for no pre orders = No advertising yet/ not many know of the pre order bonuses. Also NA has never been the strong selling point for GT games. Americans would rather play FPS's over and over again than switch between differant genres. Games like COD already have a fanbase on this gens consols so people who can only afford one game will get COD and there is a lot of kids and adults who can only afford 1 game.
But the biggest reason is because of Sony. I started seeing Halo Reach adverts in the summer telling people to pre order now for exclusive access to the beta and then the game properly started advertising 6 weeks before its release. Sony hasn't let many know that this game exists. My brother whos not a gamer but plays the GT series didn't know about this game until 2 weeks ago when I told him it was coming. He went out and bought a PS3 for it last week. Knowone will buy a product they don't know about and 90% of casual gamers don't check gaming news sites
