cvxfreak said:It's possible, but I don't think that one is set in stone. GT4 sold 1,066,749, and only a few PS3 franchises have met their PS2 predecessors' sales. I'll have to see the hype machine that SCE builds for the game closer to release.
Going by PD's info GT4 sold 1,270,000 in Japan with Gran Turismo 5 Prologue selling 740,000 as of December 2009.
World Wide
Gran Turismo 4 sold 10,980,000
Gran Turismo 5 Prologue sold 4,650,000
Pretty good for a SCEJ studio.
