I may be mistaken, but weren't both Gran Turismo and Gran Turismo 3 practically launch games for the PS1 and PS2 meaning you could not purchase a PS1 or PS2 without having to buy the game with it? If so, then that explains their numbers.
As for Gran Turismo 5, I am lowballing it a tad with my predictions at 425k first week and 4 million lifetime to the chagrin of CGI-Quality and others on another thread who use Prologues sales, point out the VGCHartz preorder charts are for the Americas only, and fervently believe Gran Turismo 5 will be just as big if not bigger than the last Gran Turismo game.
I just don't think Gran Turismo 5 will have the 2 to 3 years to be adequately bundled to pass the 10 million mark. I think Nintendo is going to crash that party sometime in late 2012. Just a hunch.
