The PS3 not only caught, but passed the 360. It's hard to believe when the 360 had a year head start and the PS3 was twice the price in the early cycle. The PS3 outsells the 360 worldwide by around 30k units take or give on a weekly basis. The ship has sailed as far as the 360 winning last generation. It is impossible for it to ever catch PS3.
