IMO no matter if the PS3 is 300K ahead in Europe or you take VGChartz/Microsoft's comments. The 360 sells at nearly a third the entry pricing of a PS3 at Euorpe's largest retailers and has been on the market for 36 months, 16 more months than the PS3.
This while the biggest PS2 sequels and most anticipated games for the PS3 are still to hit the platform and the 360 has had releases of all its most anticipated games and all hit titles on the XBox has already seen 360 sequels.
So no matter the exact figure, the PS3 performed wonderfully versus to the 360 in Europe.
