Yeah, I've been to Tokyo a bunch of times and the Xbox console and games sections are always super small. Even the amazing second hand stores.
Some other numbers I saw on GAF - crazy ratios. The Xbone doesn't have much of a footprint out side of English speaking countries really - it's basically just North America and maybe the UK where the "Thunderdome" is kinda sorta close.
