I would agree that in Europe, the PS3 will recieve a bigger boost, but GTA, although VERY well selling in Europe, didn't sell nearly as many units in Europe as the US.

Total, US/NA sold about 2.5m more copies than Europe did. Also, don't forget that the 360 still has about 1,000,000 extra consoles sold in "others"..So the impact of the PS3 might not be as high as you'd expect (but nevertheless, pretty good).
Back from the dead, I'm afraid.
