Eurogamer writes: "Sony Worldwide Studios boss Shuhei Yoshida has confirmed Gran Turismo PSP is still in development - even though it's been years since the game was first announced.
When asked where GT PSP has got to, Yoshida said, "Good question! It's in Polyphony Digital, they're working on it."
The reason for the delay, according to Yoshida, is that Polyphony have been busy with other projects. "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," he explained. 'That's been making the PSP development a little bit slow.'"
