Well the PS3 not only was a new model - but the new model was cheaper than the old one, shaving off close to 100$. That was almost a no brainer for people on the fence.
So why wouldn't it sell more than a smaller 360 model, same price as the previous Elite, with upgrades like wireless? The fact that the numbers are even close - is honestly a victory in my eyes for MS. Check the differences in the current market situation - if they manage to slow or cease the slipping lead in market share - that leaves Sony at a gap they can't close - an another price cut being forced onto them.
People have a whole mess of reasons to buy a PS3 over a 360 (blu-ray, excellent game catalog now, free PSN), and they are still lagging - and actually got their momentum halted/reversed by a new 360 model. I think people need to start realizing what MS is managing to do here. It really is something else.
