The head of the Sony-owned developer Polyphony Digital has said it’s ’very probable’ that its forthcoming racer Gran Turismo 5 will enjoy a simultaneous global release.

“The game is still under development but its release is not too far,” Kazunori Yamauchi stated, according to GT Planet. “It will be after the PSP Gran Turismo release and, very probably, it will be a simultaneous world release.”

The developer also confirmed that the game, which is expected to arrive later this year, will run in 1080p, or ‘True HD’, and at 60fps (frames per second). Gran Turismo on PSP is due out on October 1st. Those who buy Sony’s new PSPgo portable will be entitled to a free download of the game from PSN.
