It's been a while since we brought you some more news about the PSP version of Gran Turismo 4. In an interview with 1Up, Kazunori Yamauchi (the big shot over at Polyphony Digital) told the press that they're still working hard to finish the game.

Further details are missing, so we have no idea what the release date could be. The game was shown last year at E3, but since then things went silent.

Let's keep our fingers crossed for more details at this year's E3, which is only one month away.
