The 360 isn't the best selling console in Japan, true. However, both shmup and a few visual novel developers have adopted it there as the system of choice, to the point where you rarely ever see new releases of either genre on the competing platform. Given shmups and visual novels status as "hardcore otaku" games, art of girls playing the 360 is fairly common.
Isn't it ironic that the system synonymous with "dudebro" shooters in America is considered the hardcore system in Japan? It's a shame, since the PS3 is region-free and has a much better d-pad, features that would make it excellent for an American shmup player like myself, but if you want to play new Cave shooters, your only bet short of having a real arcade in your area or buying the PCBs is to buy a Japanese 360.
