Sony’s Shapiro unveiled a prototype digital cinematic camera scheduled to be released next year. The camera has a 35mm sensor and records video on SxS. Release in 2011 :(
I didn’t get any certain information yet but it seems that the camera has an Alpha Mount and you will be able to use current Sony Alpha Lenses
Sony also presented a concept prototype of the future 3D camera. It features a double 3-inch CMOS sensor, Full HD (1920×1080), interchangeable lenses, convergence control and full metadata support. Field tests are scheduled to start in July.
