considering prologue sold close to 2.5 mil....gt5 probably will reach 10 mill in its lifetime...full version will definitely sell more than the demo...it'll take a while though...but the next GT that comes out...i dont think it'll reach 10 mill...if u look at the history with GT...it's always the first one of the series on that platform...that it sells well...then the 2nd one for the same platform doesn't as sell well...but it does sell pretty damn good still....
On PS1
GT1 10.85 mil
GT2 9.37 mil
On PS2
GT3 14.87 mil
GT4 9.53 mil
On PS3
GT5 ???
GT6 ??? if it ever makes it on PS3...GT5 is taking so long to come out...
