Longevity for the 360 is self evidently a fact. However it is true that, worldwide, the PS3 has consistently outsold it this generation. In spite of a 1 year head start the gap is now less than 1.4m and closing by over 30k every week.
Of course both consoles have been outsold by the wii.
Finally, the suggestion the the majority of sales are generated in the U.S and that's what counts is palpably not correct. Last week, for instance, the U.S. account for circa 37% of sales...significant but well short of a majority.
