There is no doubt that the gap will diminish in the long and PS3 still has the chance to pass the 360 in the long run (2010 as earliest). There are two important points to look at here,
a) Is 360 persistently outselling PS3 by cumulative sales from the launch on a weekly basis? NO

The green line (360) is NOT above the red line!
b) Does PS3 still have incredible exclusives? YES
As long as the answers are 1)No, and 2)Yes, PS3 is far from being doomed.
