5D Mark iv - 4K internally recorded using HEVC H-265 / Ilog, 24p/30p/60p High data rate w/ less compression; 25 megapixel sensor count, Dual SDXC or CFast compact flash. Low light performance comparable to Sony's A7s (actually, I have seen a canon cmos imager with better low light performance - approximately a year ago) Many of the 7D mark ii improvements. 2,700 - 3,200 price range.
I have the Samsung nx1, truly a great camera. Because of the imagery from the NX1 being absolutely great under the HEVC codec Canon can take a professional low compression, high-bit rate stab at it. I know the codec will be ubiquitous within the next 2 years and thus improving the cameras usability in the future.
