The PS3 will never pass the Xbox 360 because Microsoft has the twin powers of epeen and money. If it were a case where both were equally profitable with equally profitable parent companies then you'd make a strong case that Sony has more epeen to push sales ahead of the 360. However Microsoft put their extensive epeen on the line by stating all the way back in 2008 that the Xbox 360 was going to remain in 2nd. If the PS3 looked like it was going to pass the 360 they would cut the price because they would enter into epeen protection mode and they'd be willing to sacrafice money to do it.
My prediction: Kinect came out 2010, Xbox 360 S came out in 2010 also so to counteract the launch of the Wii U they'll also launch a revamped Xbox 360 sometime next year. There has been plenty of time to put something together to this effect.
Tease.
