So it may have been a few years since we first heard about Gran Turismo for the PSP, but Sony Worldwide Studios boss Shuhei Yoshida has confirmed that it's still in development.\n\nWhen asked where the game had got to at the Tokyo Game Show, Yoshida said: "Good question! It's in Polyphony Digital, they're working on it."\n\nHe explained: "They have been working on Gran Turismo 5 Prologue and Gran Turismo 5 for PS3, so they've had to focus on finishing up Gran Turismo on the PS3 side. That's been making the PSP development a little bit slow."\n\nHowever, he's not going to push the boat out and tell us when we can expect to see it released to make up for the wait, and wasn't even prepared to tell us if we'd even see it within the next year.\n\n"I cannot comment," said Yoshida.\n\nWell, we've waited this long. What's another year or two?
