Yea, but In Japan, you need a domestic product to sell well.
Well usually, don't iPads and iPhones sell well in Japan? Or is it South Korea and China exclusively that they sell well in?
In USA being domestic is a big help, you only need a half decent product to compete and viola. I don't knpw if Sony can ever reclaim USA anytime soon, but you never know, no one could have guessed Wii could have done so well in USA.
