I would say around 10 at max.

"Only" over 10 million. I don't think GT3 even reached 15 million.

Ugh that's an ugly Mercedes... is that some concept car?

Anyhow.
15 million is not possible unless they force bundle it in at least 2 regions (ie everone that purchases a PS3 has to get GT5 with it)

10 million the extreme high end of sales if it is not bundled at all (though it will be), it would certainly not manage over 10.5 million.

with some moderate bundling, ie perhaps a couple month stint of force bundling or long term value bundles. (the likely scenarios) then I would say 12 million is the high end, and roughly 9-10 million is probable.

7 million is dead cert, I don't see any situation where it won't exceed that.... personally I expect between 9 and 10.5 million.

It would have easily hit 10 if it launched this holiday. Now, I'm not so sure.

15 is out of the question, but then it always was.

If sony keeps up the strategy of pre games sales and what I mean by this is releasing something to show a minimum sale for the whole product they can gain alot of sales for many games.

GOW3 will be shipped after the new GOW collection if that is to sell 2-5 million it is good news for GO3.

GT5 had/has GT5 prologue which sold 4.5 million is barely a fraction of the game so we can assume the game to sell minimum 6 million and maybe be the best console pusher sony has had for the ps3 yet.

7 million.

Maybe 10 million total.

Even then, I think that may be much. I'd say around 8 million.

It should do about 8-12 Million...

Definitely either over, under, or equal to ten million.

17-25 million
