nVidia is selling the Fuji here: Fujifilm FinePix REAL 3D W1. It takes just SD video, but it is optically aligned, integrated, with matched characteristics of the optics and sensors as well as genlocked. It fits into coat pocket. In addition it has glassless stereoscopic preview in the finder. I am not aware of any similar solution that can be had for their price. Reviews are somewhat mixed though. I think that such product and much more are needed or 3D might fade into obscurity yet again.
