I know you weren't responding to me here, but I was simply challenging the assumption that the PS3 had a more appealing games lineup for Eastern tastes (at this point in time compared to 360). Aside from Hot Shots Golf and Resistance (which is a FPS, lol), all of the most popular PS3 games in Japan are on 360 as well or coming in the future with added content.
It's a similar situation to the 360 in Spain and Germany currently - if you look at the PAL charts, people are buying PS3s over the 360 for multiplatform games (COD4, AC, PES, FIFA, DIRT, etc) that are actually better on 360, not because of the exclusives like Ratchet, Heavenly Sword, LAIR, etc.
I'll contend that it has much more to do with what MS has done wrong with the Xbox's image in these regions than what Sony has done right. As in, people aren't buying the PS3 in droves just because of Sony branding, Blu Ray, and hardware stability, as it isn't exactly lighting up the charts in either region. People are avoiding the 360 specifically because it's an Xbox.
