I had no idea this game was coming to the XBox until now. Actually I did hear a rumour going around a few months ago but nothing official. One of the only reasons I kinda liked PS2 was becuase of it's Gran Turismo games. Looks like it's coming to XBox, lol. Their loss, our gain.
There's lots of stuff to check out in the link below.
