Pretty much a given it will. First GT of this gen with no serious competition.

One of the few games that sales well in every market in the world.

My take is:

5 million - given.
10 million - possible.
15 million - improbable.

So the answer is a big huge maybe.

The sales of the game are justified by the sales of the console. Look at the front page for more information.

@gilgamesh

so basically wat u have said is...the more popular GT series will not sell more than the less popular MGS series....GT series has sold usually 2 time more than the mgs series with the same given userbase

GT series will definitely sell more than 4 mil that's for sure...2-3 mill in america......2 mill in europe and about 700k-1 mill in japan....probably wont' make a mill in japan....

Um are you sure you read that right, I already explained where I got the number and why it was so low and the reasons why I expect it to be much higher then what I came up with. I just didn't take everything in account like price cut, bundle, release date, the amount of PS3's by the end of this generation because nobody knows the answer to any of those questions.

yeah i read it i get wat ur saying..i just couldn't agree with the 2.6 million part...it definitely will have more than 2.6 million within the first 10 weeks of release...but bulk of the sales come from within the first 10-20 weeks of release...later on when more ps3 will get sold..the attach rate will definitely come down...but here is reason why i think the 2.6 million sold will be disproved...

the current MGS4 #s would completely destroy that theory...MGS4 should have sold about....1.3 million....it didn't...it sold 3.63 million so far...

also if u go by attach rate.....GTA4 would completely destroy another theory..GTA has an attach rate alittle above 25%...big name game with history usually dont follow the attach rate theory...and GT5 has history...and a big name game...so it will definitely sell more than ur 2.6 million prediction

oh yeah...i was talking about selling more than 4 million in defense to the 2.6 million have said...not in defense to it will sell 9 mill later down the road...i should have specified....if ps3 grows to about 65mill..then i can see it happening....

I was just going by how the attach rate for the PS2 was with GT3 and GT4, maybe the PS3 has a different attach  but the numbers I got was if the attach rate was the exact same as the PS2 for the PS3. So if it is the same then it should be that out of 27.5 million PS3 users there should be 2.6 million that will own GT5 (this is if there was no price cut by the time the game released, if it was not bundled and if the game was released at the begining of 2010). That number is really low I know but I'm just going by what the attach rate was for the PS2, the PS3 will likely be different and the number should be higher.

I know what you mean with your MGS argument and that's right, and it kinda proved that the PS3 has a better attach rate then the PS2, but that is just one game.

Edit: off to bed

You think the full version will sell as much as prologue, lolol. Going by PS2 attach ratios is horrible. MGS4 would be projected at what, 1m lifetime? Haha.

At least take the Prologue attach ratio and use it for GT5, then you can get at least a bit more accurate.

By the end of the gen, definitely. The first Gran Turismo on each platform sells incredibly well.

It will definetly sell over 10 million it will be amazing just like all the other gran turismo's
