- The man behind the Gran Turismo series, Kazunori Yamauch
(from Polyphony Digital) said when interviewed by Joystiq that it's not that easy to develop on PS3 that they've had to put GT for PSP aside a little bit. On the PSP version he said "we are still working on it, but this will be after GT5 on PS3."
Gran Turismo is also one of the few games that run at 1080p and 60fps, he said that this was a must have because when you're driving at high speeds you must be able to see detailed objects in the distance. He also said they had ideas for PSP interactivity with the PS3, most notable was that he thought it was possible for someone on the PSP to compete in the same race with someone on the PS3.
To quote from the interview: Interactivity between PSP and PS3. One of the examples they showed at E3 two years ago was the idea of a rear-view mirror in a racing game... *laughs* ...so that example probably not being the best application of the PSP, have you considered any other kind of PSP interactivity with the PS3 and GT5?
Well, one example would be for people to utilize replays of their race experience. Take that outside the home, whereas at home you would need the PS3, but they can take that away and share. Another would be - and we would need to do further research, we're just talking ideals...
