Gran Turismo 5 will pass 10 million lifetime sold in 2013

Only because GT5 need 5 years to make doesnt mean GT 6 will take the same amount of time. Polyphony hired people too, not only Turn 10.

And for the productiosn costs. Most people dont expect next gen to be much more powerful so i dont expect nexgt gen gamesto be so much more expensive to make.
