In regards to the Samsung NX1, I'm considering a purchase, but I'm a bit curious about your comment regarding "3. Unnatural motion cadence when panning or recording a moving subject (deal breaker)."   Is this in reference to some form of extreme rolling shutter when recording UHD or 4k?  
I've seen that the 4k rolling shutter is pretty bad on the Samsung but its also not great on the Sony A7 series.  However, the Samsung 1080p rolling shutter is one of the best among CMOS sensors.  My thought is that during scenes with extreme action or during lots of hand held shooting, I could drop to 1080p to compensate.
Or does motion cadence refer to something else?  To my mind, something shot at 24 fps at 1/50th shutter speed should be pretty much the same across cameras unless rolling shutter plays a major role in what is perceived by the viewer.
I'm very curious in regards to what people are referring to when they reference motion cadence.  Seems a very nebulous trait of a camera and I'm very interested in what makes good cadence vs bad cadence that would constitute a deal-breaker for a certain camera.
