It very well might not, but who really cares? Eventually, the video game world is going to wake up and realize that Japan is not really that huge of a deal at this point. Yes, there are a ton of top-tier Japanese developers, but if Microsoft has proven anything, it's that this whole, "As it goes it Japan, so it goes worldwide" idea is nonsense. Japan is a tiny market relatively speaking, and their consumer habits are fairly divorced from the US and Europe, so even if the PS2 does continue to outsell the 360 in Japan, it really proves nothing besides that the Japanese market is an anomaly.
