Polyphony Digital has reiterated that it plans to return to its PSP Gran Turismo project once it has done a bit more for PS3.
"We are working on it, and we will get around to it eventually," he said.
GT for PSP - once known as Gran Turismo 4 Mobile - was pretty heavily billed in the system's early days, but just over a year ago Polyphony said that it was setting the project aside until it had finished a GT title for PS3.
Claiming it had the game at "the stage where a GT4 equivalent runs on the PSP", the developer said that once a PS3 GT was out of the way, it would "return to, and jump-start, development for the PSP version".
In the mean time we've had Gran Turismo HD Concept arrive on PlayStation Network, while Gran Turismo 5 Prologue is due out on Blu-ray and PSN later this year.
GT5 is expected some time after that.
