I keep saying this over and over again in different threads but Japanese gamers are no longer interested in home consoles. They spend their entire day at school/work and when they come home they eat and then sleep. The weekends are mostly just further study and/or second jobs. Japanese culture is moving away from home consoles and is completely embracing portable solutions (either proprietary like 3DS or Android/iOS games).
I think we need to STOP using Japan as a gauge for anything related to home consoles. The west is obviously more interested BY FAR. I mean you know its a sign of change when Sony launches everywhere else in the world MONTHS a head of its own native country for the Playstation. I remember when the Playstation was absolutely a Japanese foundation and expectation for gamers in Japan and now things have changed.
What you said was basically what I'm trying to say
