As a Bicam user myself, i went to see Silvestri at the Photokina, where they showed the prototype of the BicamIII, to be released later this year. There was a teaser on facebook already, the press release is now online.
The grip has wooden inserts and the body now has side shift (on the rear standard) too.
Until now you needed the sliding back for stitching or the flexibellow (which has side shift and tilt on the front element).
I'm looking forward to this upgrade, the Bicam with the shiftable viewfinder and a 35mm lens is a nice "point and shoot" wide-angle cam, but sometimes you just need these few mm more, and then you forgot your sliding back at your studio.
