As to whether or not the camera supports an active mount, all the features needed are certainly built-in. If you zoom in on the BHPhoto image, you'll see electronic contacts inside the lens mount. There are also OIS and iris buttons on the side which would further reinforce the use of an active mount. I would assume this hardware would be to support features on micro four thirds lenses since that is the mount it comes stock with which would not have the optics to cover the sensor. It will be interesting to see how all this works out.
