I think Canon missed the point on this one. The DSLR video popularity was not because we all really wanted DSLRs as video cameras. They SUCK for video. No ND filters, no xlr inputs, line skipping because of 18MP sensors, awkward body styles, manual zooms, horrible focusing options, no peaking, no articulating screens, bad audio control and preamps, crappy recording formats for editing and grading, and all kinds of other stuff. The reason we all got excited is we were able to get impressive video quality from a $500 t2i and even better quality from a $2500 5D mark II with only a $400 prime lens. No one wants a pro video DSLR for $15,000 with all of the same issues like lack of ND filters, high res sensors, no xlr inputs and horrible focusing options. I'll deal with those shortcomings in a cheap camera but for Gods sake, if you are going to make a pro video camera, make a freaking pro video camera with pro video camera features. I can't believe Canon would do this as a company who makes great video cameras. 8 years ago I had both their XL1 and GL1 video cameras and they rocked for less than $3000. If you can't improve video in your current DSLR cameras without vastly increasing the price, then do what Sony, RED, and Panasonic are doing and put that awesome full frame sensor into a real video camera. I guess that is what they were attempting to do with the C300 but that camera is way over priced as well.
Guess we won't be seeing much if any video improvement on a 7D mark II, 70D, or T4i if it takes a $15,000 camera to make improvements.
