I think it has to do with the fact most of X360's AAA games are in the FPS genre, whereas the PS3 has AAA games pretty much in every genre. It only makes since that a lot of the 360s userbase is going to buy the flagship FPS on a heavy FPS system. You should also try comparing new game sales in "others" the PS3 version outsells the 360 version. It's also funny to see multi-platform JRPG games sell better on the PS3, even in the US; FF13 was a perfect example of this.
