The 360 does well in NA and not in Japan because of games. NA game preference is different that Japan. NA plays a whole hell of FPS's and such. 360 bread and butter. Whearas Japan is more into RPG's, (DQ & FF). Two very different markets. If the 360 can keep the sizeable leads it now has it will eventually sell well in Japan because there will be many more PS3 ports of games from Japanese devs that will sell well in Japan. However, if Wii closes that gap by year's end, I think it will happen, then those ports will stay on PS3 for this year and may switch to Wii/DS exclusives next time around like DQ did.
