Gran Turismo 5 Prologue Trade in For Gran Turismo 5?

Highky doubt it. Gran Turismo current progress is at 65% as told by sony and won't release till next year March. Prolouge was release in 2007 so the progress from back then is extremely low. As you can see I belive proloyge only came with around 50 cars or so(can't remember) the final product will be packed with a whoppin 1000 cars(might be even more). So a trade in for the final version won't happen.

No, you wouldn't get much trade in value out of old Prolugue, although I remember that there was a deal like that for Gran Turismo 4, you traded in two old games,(could be really old or cheap, just had to be PS2 games) and got GT 4, for £1.00, in GAME, I don't know if that promotion was run anywhere else:)

So maybe they might do something like that again, but I think you'll have to trade in at least two old PS3 games:)

No way. Prologue is "just another PS3 game." You'll need to pay full price and trading in Prologue will be like trading in any other ordinary PS3 game.

Maybe a 5pct =/.... Lol
