Can someone please tell me why Zeiss, Contax, Rollei, Leica, Voitander, Linhoff, Schneider etc dont all band together and create a new 30mm x 30mm specification for lens mount and film/digital backs (ala the 4/3 format by Olympus, except a larger sensor size).

Im sure anyone who has held one of these crafted cameras would love a "no stress", upgraditis free solution in the current disposable digital camera market place.

Together they would be a force no?
