Polyphony Digital's US Producers, Chris Hinojosa Miranda and Taku Imasaki, answered some questions submitted by readers regarding Gran Turismo PSP over on the US PS Blog.
To quote: Could we expect any compatibility of Gran Turismo PSP with Gran Turismo 5 (like Resistance: Retribution with Resistance 2)?
Polyphony has always pushed the hardware boundaries of every console it's been released on...and while this isn't really answering your question, it does leave it open for you to imagine the possibilities.
Is GT PSP going to have DLCs (such as new cars, tracks, etc..)?
We're planning on having 800+ cars right out of the box, which is pretty much a lifetime's worth of racing (I'm still unlocking cars from GT4). With that sort of breadth and reach of options, having DLC would be like tossing water into the ocean.
Will cars get damaged on GT PSP?
Damage? No. 800+ cars, 35 tracks, on-the-go awesomeness, and a lifetime's worth of racing, yes.
Will we see Porche, Lamborghini in the PSP version?
Our car selection is pretty broad - there is a lot of candy, that's for sure - but as far as flavors, you'll just have to wait a bit more.
Will there be a downloadable demo of Gran Turismo for the PSP?
We wish we can provide one, but at this time, there are no plans. We are focusing our efforts on Gran Turismo and GT5.
It appears that the AI car count is 3 cars on track. Counting you, there would be 4 cars in the race. Wouldn't it have been better to drop the framerate of the game from 60 to 30 and increased the car count?
We went through many experiments but came to the conclusion that having three opponents gives you the best portable racing experience while maintaining the Gran Turismo level of quality.
Cmon fellas... GT5 Prologue update? Eh, eh? Custom soundtracks? Maybe trophies, a lobby system? Screenshot function?
Sorry, we're around the bend and down the straight: the team's main focus at this point is making sure GT PSP (and GT5) are in your hands.
