According to latest rumors posted by Andrea on SonyAlphaRumors Sony is about to launch a new NEX Full Frame system. I am trying to figure out if it means that it will use the same E-mount or some kind of other mysterious trick to make it work on an E-mount. No idea yet, but I think Sony is going to surprise quite many of us at Photokina if they bring it for real! It would probably the first cheap “Leica” alternative of the history :)
