Apparently Art lost interest. For anyone else interested a few details:
The pano cameras were updated, the door now opens wider and gets out of your way better when using the GG, the finish is better and the cold shoe for the viewfinder is in a more decorative alcove. However make sure that the cold shoe aligns optically with the lens. The early model had some problems there.
The viewfinders have been updated and are better. They have far less distortion that the previous WA version. In light of the up coming release of a rise and fall shift adapter, you can get lens cones that have this added in feature in mind. They are 10mm shorter and will fit with the shift adapter, if you decide against using the shift adapter the cones come with a 10mm spacer instead.
Film flatness is excellent with this camera as the advance system consists of 2 simple knobs on top, so you can turn them in counter rotation to each other and tighten up the film. The pressure plate holds the film flat and I have yet to see any scratches on film.
The GG uses magnets to attach to the camera, make dead certain though that the GG is in the right place and FLAT. Otherwise it's a great and simple design. Speaking of simple the camera has just 8 moving parts, the focus ring, the 2 film knobs, the door, the pressure plate, 2 rollers for the film and the slide door for the peep hole. The peephole is needed for advancing your film.
Lens cones are removeable by removing 4 nylon screws, I assume the use of nylon is so that the threads in the camera body do not get stripped or cross threaded. If you intend on changing lenses order extra screws. Changing lenses can be a little slower than you might be used to, but it's not that bad. I prefer not to change lenses so I bought dedicated bodies for my most often used lenses. You can use lenses as long as the 400mm tele fuji, I'm awaiting delivery of a cone for the 360mm tele nikkor.
All in all a pretty good system and reasonable in price.
