My guess is between 6.5 million and 8 million.
Driving sims are slowly losing their sales and popularity (esp.. in the Americas). Unfortunately shooters seem to be gobbling up the lost sales for the time being. This along with the best selling game on the PS3 selling under 10 million units give me my figures. Not to mention all of the delays that GT5 has had and its stiff competition.
Just because a game doesn't do 15-500million sales, doesn't make it a bad game. I am certain that GT5 will be the best GT game ever made. Its just being served to a much more shooter based client list and its a year and a half late to the party.
The only way it will break 10 million will be if Sony bundles it for a very extended amount of time.
