Announced in early February, both the Silver Satin PS3 and Xbox 360 Arcade are now on sale in Japan. The SS PS3 is a spec-for-spec equivalent of the existing black and white Japanese models. However, this is the first time the entry-level Xbox 360, already available outside of Nippon, makes an appearance on Japanese soil. Guess which one Japanese gamers are more likely to buy? Right, the Wii.
