Well, the Wii destroyed the X360 in NA so there goes that theory.
While some people do prefer to buy products built in their own nation, I would imagine most put quality/price/features first, and then national preference second. The X360 is a western centric system with games that most westerners like (Halo/Gears/Rock Band timed exclusive). Even if they put more Japanese style games on the system it already has that image. It is like the Nintendo is kiddy image that Nintendo has had to struggle with. If Microsoft can shake the image of not having the style game desired and makes better hardware next time around they have just as good a chance as Sony as being #1 in Japan.
