Well the PSP has been dominating in Japan these past couple of weeks, so its not a surprise really.
The DS looks like it has hit the saturation point. I think everyone in Japan owns a DS...lol
And the consoles, well the Wii is doing somewhat good. It needs more software released and the same can be said for the PS3.
The Xbox 360 is just *thumbs down* in Japan. It's getting some strides but not quite enough.
