Sony launched dedicated Playstation 3 sites in Japan.
So far I could not find any new details on the official Playstation 3 site or the so called Concept site (playbeyond.jp).
If you do not speak Japanese the sites are not that useful. On the concept site you can download a PS3 wallpaper. The official PS3 site features the known hardware specifications and the game list.More details about the Sony Playstation 3 can be found in our PS3 overview report.
