lmfao, i cant believe some haters think it will only do 3 million. stop trying to hide the fact you hate playstation3 and cant take the fact that is has one of THE biggest selling franchises! GT5 will be massive! the only game on xbox that will compete with that is of course the xbox's monster, HALO.

 That's 2 very good points I forgot about in my prediction. That means I probably overshot it a bit, to a 9-11M sounds more reasonable than 11-13M when thinking about it.

Perhaps Gears of War 2 will be capable of touching it, as well.

GT has been losing sales with each iteration, yet if they get damage in instead if time penalties i think this will start shifting around a 50% attach rate. Very high i know but speaking to people and i think you all (those that have played any of the 4 GT games) feel the same, chuck in damage and this turns into a must have.

 1. GT has not been losing sales with each iteration, it peaked at GT3, since that there has been 1 main series, and 1 prologue. No matter how you count it, it has only been losing sales with 1 iteration.

2. A 50% AR is close to impossible. No game that hasn't been officially bundled has beaten 33%, other than Halo 2 and SM64 (at the end of their selling lives)   

I'll say around 7-8 million copies.

Im thinking 6-7M.

GT3 was the first AAA must have title for the PS2. That will not be the case with GT5.

GT3 had no competition on the PS2 or other consoles. GT5 will have Forza 2 (probably Forza 3 is waiting to be released as well) on the 360. Forza 1 was considered superior to GT4. Forza 3 will be very comparable and on a console that has a larger install base.

GT5 will not create a big rush of new PS3's being sold. Around 30 million PS3s will have been sold by the time GT5 releases. Much of the GT5 sales will come from this group of PS3 owners.

OK, i should have said each iteration on each machine. GT was around 10.5 mill, GT2 around 9.2. GT3 around 15 and GT4 around 10.6. Yes 50% is silly high and i have forgotten to factor in those who purchased the PS3 for a BDD player. I do believe if there is damage the attach rate will be uncommonly high though.

hahahaahahahahahahaHAHAHAHAHAHAHAH. Are you serious=? want to bet on that?

Yeah, it will be incredibly high. For highest attach rate, you can probably say something like this.

Everything on Wii, but the Wii series is discounted, as it looks like it will get at least an userbase of 100M, and nothing but Wii Sports/Play and possibly fit will pass 30M (maybe not even 20M).

X360 and Ps3 will end pretty equal.

So the best selling Ps3 or X360 game is likely to be the one with the highest AR this gen.

As this gen is the one with the highest AR, it may be one of the highest ever.
