there is some dude on ign who says this
"Guys!! Hopefully this will shed some light on the debate-
I have been following this thread (and GT4) for quite some time now and really really hoped the game was coming out on the 18th- I happen to have a friend who works at a local ebgames where I live (studio city, CA) and I asked him about the game and HE TOO mentioned having boxes in the back of the store labelled gran turismo that he claims arrived about half a week ago. I thought he had read the thread and was f'in with me, so I made him take me to the store, and to my surprise he did, and to my even further surprise (and unbridled joy,) there actually WAS a box labelled gran turismo. Even better, I snuck my cheezy camera phone in and managed to take a few pictures- I didn't feel too bad because Jason doesn't seem to care about his job at ebgames all that much (he described it as the only possible place you could be surrounded by video games and still be in a hell hole) lol. I'd dispay the pics or link to them directly but I guess I have to be an 'insider' subscriber to do fancy things like that. Nuts to that!

Rejoice! Gran Turismo IS coming next tuesday! After eons! I truly did fear that the PS2 was going to be discontinued before release of this game."
