gran turismo 3 was bundled for a long time, and stuck around for the whole console generation, I can still go buy it in stores. So you would have to consider the whole user base as it is now, which is around 140 milion consoles. Halo 3 is up there with a mere 30 million. GT5 won't be near the same amount of success. I think prologue is a very good indicator of what it's sells will be, I would be very surprised if it sold more than a million or 2 more than prologue.

It well sell at least 4-5 mill more than that Prologue.

 

you say that with such certainty, do you have a time machine?  I honestly don't see how it could sell that many.  With a lifetime userbase going to be about half of what the ps1 was, I don't see how it could match the sells of the previous games. 

Plus, the racing genre is nearly as popular as it once was.
