I have my doubts that it could do as well as the previous iterations but here is why I think it could reach 10 million.
Preorders are at 144,000 with 12 weeks to go. It will likely reach 250,000-300,000 preorders in NA before release.
Prologue sold 145,000 the first week in the Americas. So GT5 is looking to launch twice as big as Prologue in the Americas
EU will likely account for 55%-60% of the total sales, much like GT5P.
Given this, we are looking at a 1 million first week and sales twice that of GT5P. So around 8-10 million total.
GT5 will sell well and be the best selling PS3 exclusive but 10 million will depend on legs.
2011 Predictions
Wii: 17m (100 million total)
360: 13m (63 million total)
PS3: 15m (61 million total)
