If you are using the Chrome browser, you can go to the Japanese language Fujifilm page of discontinued products and select “Translate” at the top of the browser window.
The Fujifilm W3 was officially discontinued in May of 2013. At this time, there appear to no longer be any major vendors producing any 3D still cameras.
3D enthusiasts can still buy the W3 from inventory (price has fallen to about $160, new, at Amazon.com). The Lumix 3D1 is widely available on EBay, but usually Japanese language only version. The camera’s interface is almost entirely icon-based so the language issue is not a big problem. You can also still get a GoPro Hero2 package and 3D sync cable from GoPro.
The other alternative is to build your own using two older Canon cameras and the StereoData Maker version of CHDK hacking toolkit and a home made or purchased USB synchronization cable.
