If BD couldn't save the 360 in japan, i don't think anything will. Bebpo must be in convolutions right now :lol
Still the lack of Zelda in those charts is extremely worrying, but atleast Nintendo has pretty much the rest of the chart, Microsoft doesn't have anything else out there.
If Microsoft is to have a 'chance' at Japan, they'll need to launch 3-5 Games aimed at the Japanese market all within 1 month of each other and perhaps bundle one of them with the 360.
But... quite frankly its no use, Nintendo has Japan by the proverbial Balls.
