3 or 4 million lifetime.

I think 6 million is too much for NA. 4 million sounds more realistic, and the fact that GT5 will have Nascar, WRC and 1000 cars will mean that it will be bigger in NA than any other GT.

But still, 6 million is too much. or anyone doubting GT5 will do more than 2 million in NA, look at the pre-order numbers.

NA?

I would say no more than 4 Million.

Americas ~ 2 mil

Others - 5 mil

Japan - 1.5 mil

WW LTD ~ 8.5 mil

You have no idea how big and strong a franchise GT really is, 2 million in NA will be nothing for GT5.  To double prologue sales will be rather easy. 

WTF are you talking about.

- What are these massivly selling SCEA gmaes last gen that the current ones are failing to match ?

- And no SIM has ever done anywhere near what GT did, best comp was Need for Speed and it only did like half of what a GT game would. 

There is no trend to reverse, GT always was a differant beast compared to the others. 

No, 6 million is virtually impossible.  I could see 3.5 million max.

GT3 sold more than 7 million in NA, GT4 nearly 3 million.

For GT5 I predict 4-5 million in NA.

Reasons: After this long development time I think many many people want a new GT. I also think there won't be a GT6 on PS3 and #5 will sell for a very long time - in all 3 regions it will have better legs than any other PS3 game. This game will sell excellently bundled and unbundled.

I would say that 5 million LT is a pretty safe bet. But it could do worse and better to. I see it doing a little over 3 million best case and little over a million worst case. I hope that I am wrong but the PS3s installbase is to tiny in the US, and racers are not what they used to be

My Initial guess was NA would only sell 2 million but seeing the numbers that GT3/4 sold in NA I'ld go with

5 million NA
10 million Europe
1.5 million Japan
