I want to point something out that people seem to forget all to easily:
-The week ending before the PS3 launched in Nov '06 was the closest the PS3 has been to catching the X360 ...EVER.
-The week before PS3 launched it was 5,207,486 behind the X360, after launch week it was 5,289,779 behind.
-Today the PS3 is 6,629,183 behind the X360, it was actually closer throughout most of the summer last year (2007).
-The farthest the PS3 has been from the X360 was 7,366,299 for the week ending Nov 3rd 2007.
The PS3 is absolutely making up ground but its still trying to win back what it has lost from launch. I realize that a measured analytical approach isn't quite as much fun and all but you might be surprised at all of the interesting things you notice.
I think the PS3 will pass the 360, I don't think it has a chance in hell of doing it this year but it most likely will eventually. But some of you are way ahead of yourselves in this celebration of a comeback. The PS3 is merely on the road to a comeback and has a long ways to go to complete it still.
