GTA IV PS3 pre-orders outnumber Xbox 360 orders by 2 to 1

[DragonLord]

The game will definitely sell a lot more on the 360 than the ps3, but that is too be expected. It's not that popular in Japan (like DMC4) so it won't see a huge boost from the ps3's most dominate market. That leaves the US & Europe. GTAIV will sell more on the 360 than the ps3 in the US by probably the same proportion DMC4 did....(360 will probably sell 50% more than the ps3 in US). I expect GTAIV will sell slightly more on the ps3 in Europe unless it is $10 cheaper like happened with DMC4.

But I do expect the attach rate to be higher on the ps3 version.
