With 6 to 7 million PS3's sold in Japan to 1 Million for the 360,

^ Well I can't really see the 360 moving too many units in that time. I mean, it's got to 1 mil in 3 years. And surely this upsurge for PS3 would have a negative effect on 360 sales as well, causing the 6:1 outcome to be possible (although no I dont think it is all that likely myself).
