Sony's second conference is well underway now, and already details are pouring out from it. Right off the bat with PSP stats, Polyphony came out to talk about some PSP features, but has something special to announce.

Gran Turismo 5 will be out for PS3 in March 2010, sorry no release date this year...They noted that its to ensure a complete game when it launches. 20 locations with over 70 tracks, cross platform communication with PSP, and of course the best physics engine to date. They are also including an single player and multiplayer arcade, Gran Turismo mode (unlike the PSP version), and some other features like Youtube intregration and photo viewers.

A worldwide release date has yet to be revealed, stick around!

Update:

-Videos will be capable of exporting to PSP as well as youtube.

-Hybrid and electric cars will be included in the game.

-Private rooms for online modes, the most requested feature of Prologue.

-The opening sequence was shown, lots of sparks and visuals with a up beat song to push it along.

-Still no world wide release date as of now.
