"We have a PS4 version in mind for the future" Polyphony Digital president Kazunori Yamauchi told GameSpot.
"But for this holiday season we thought that it would be best for users to release the PS3 version," he added. "I thought the best scenario would be for the game to come out, and we're planning to have new content, and DLC every few months."
The PlayStation 3 version of Gran Turismo 6 is due out this holiday season. As for when a potential PS4 version could arrive, Yamauchi said it may not be for some time.
"Once the players have thoroughly played out the game, if the PlayStation 4 version just came out naturally in the process, we think that would be the best scenario for the game," he said.
Regarding whether or not player progress could be applied from the PS3 version to the PS4 version, Yamauchi said this would "probably" be the case.
Separately, Sony announced today that a demo for Gran Turismo 6 will launch in July. No further information about the pre-release trial was divulged.
