Also, the 360 won't be selling 12,000 consoles a week in Japan in this console generation. It has been out close to 3 years already over there and only managed to sell 0.65 million consoles there while the PS3 has only been out close to two years and already sold over 2 million consoles there.
Secondly, if the 360 gets a blu-ray drive for gaming, then Halo Chronicles and the other Halo Games and Gears of War I & II will be coming to PS3.
