It's good to see and hear about this, regardless of price and whatnot. Just great that Fuji is still developing film cameras. Seems like sort of an extension of their GW/GSW line in a way - wide angle, fixed lens. Too bad it's not 6x9 too. It would be sweet to see them do an updated GSW690IV with a 43mm lens or something like that. ;-)
Look at the lens specs on this one though - 10 elements / 8 groups- that sounds like a biogon-style design to me. Clearly it will be excellent I'd think, and undoubtedly more expensive than the tessar in the folding version of the camera.
Still, a Mamiya 7 seems like a better choice in basically every respect.
