To compete with Panasonic’s AG-AF100, Sony is releasing an unnamed camera which accepts E-Mount lenses including Sony α lenses plus Minolta, and Konica Minolta.  They are looking to release this camera the Fall of 2010, well ahead of the April 2011 release date mentioned at NAB, which makes me believe that this will not be the only model. Little else is known about the camera, and the body in the video/pics is assumed to be a prototype.
