GT5 for sure to sell more than 10 million. Only things it needs is huge marketing from Sony like Microsoft did for Halo 3. Sony can use money they got from GT5:P to promote GT5. If everything going smoothly i'm sure it will sell 15 million.

well a supercar blowout in major cities would be a good starting point, but in the uk the new topgear series will feature gt5 heavily imo.

the chance to test your times on the top gear test track is a system seller on its own, of course they can again open the gt academy the hype around this will be insane.
