I don't think the system is doomed, my guess is that Nikon will do what they should have in the 1st place, the 1" sensor will be transitioned off to High end P&S Cameras to compete with the Sony RX100 as that camera has proven to be very profitable for Sony, (it's still selling above $500 higher than most MILC) and the 1-Series MILC will get an APS-C sensor to compete with the likes of Sony, Fuji and the new Panasonic GX-7.
