Quite right. And if a lower-priced Panasonic GH4 can record 4K internally, why not a 7D II?
Video is a necessary reality with these cameras. I know it is hugely unpopular with many photographers who don't care about video, but if Canon is going to include video functionality in all their DSLRs then it is not too much to ask that they implement it well (keeping pace with video standards and including basic features like focus peaking).
While a DSLR may suffer from rolling shutter disease, there really are no reasons why a new DSLR shouldn't be able to record 4k video, managing at least 24fps, 25fps, 30fps. Possibly even 60fps.
The read-out speed is possible, and the chips fast enough to process the data. The used memory cards would decide what video compression level that would be required. While current blu-ray disks with full-HD can be streamed over 100Mbit/s networks, a number of memory card technologies can do 100Mbytes/s or better - so at least eight times higher bandwidth than what media players needs for full HD while the 4k video has four times as many pixels.
