Polyphony Digital is still working on the PSP version of Gran Turismo. No, really! Series creator Kazunori Yamauchi confirmed as much to us during last year's Tokyo Game Show, blaming the portable racer's vaporware status on the Gran Turismo 5 time sink. Don't expect much movement on the mobile front until Polyphony makes it through the post-Prologue development chicane.

"We had been developing the PSP version, but the problem was that the PS3 version took much more time and effort than we had first imagined," Yamauchi recently told Eurogamer. "So that's been delayed - I don't think we'll be able to make the end of this year for the PSP version, but we are working on it."

If and/or when the final product eventually arrives, Polyphony Digital hopes for it to have an online component "linked" to the PlayStation 3 version. As promising as that sounds, we're still going to file this one as a DNF until we see more.
