Gran Turismo probably won't make any cars themselves. They might get the rights from the manufacturers for certain cars and put them into the game, however. I'm unsure how many they might put in, but I am hoping for at least one current LMP1 car and an open-wheel racing car.
(off topic)Didn't Sony say something about 2015 and the PS3 ending online? If so... All I have to say is PD seriously needs to get the ball rollin with GT6.
Yes I am with you here SS, I am a big GT fan but I can't see to much more than this with only a few mths to go. Maybe we might get lucky around the 1 year anniversary and see something but I would temper expectations. Think GT7 will be where we see the new assets that are locked away at PDI studios
