Canon broke the mold with the 5D2 and 1080p, but they really haven't done a whole lot since (with the exception of DPAF and live video AF... which is huge, but still). I didn't start out doing any video either, but my work afforded opportunities to do simple video as well under a one man operation. I shoot 4k with the DX2 presently and get fantastic results, but it's frustrating not to be able to record externally with it since the old original 1DX with a modified firmware for twice the price was so capable and three years later Canon still decided to lock that capability out as a marketing decision.
Having a compact body like the EOS R with 4k capability and a stellar output smokes the 1DX2 with the exception of a bigger crop and no 4k60. But at 4k30, it's a great camera and I have zero complaints with its specs.
What I would like to see is an RP with similar specs in that regard. We may not get 10bit 422 and Clog, but that would purely be a marketing decision, and I would likely expect that.
No 4K isn't universal, but understand that SHOOTING in 4K and then rendering to 1080p in post is still notably different (better) than shooting natively in 1080p. There is far more depth and detail going that route. That may not be a big deal for Vlogging but for wedding people and those of us doing small commercial work, it DOES matter.
I own the DX2, 5DSR, 6D, 5D3, 7D... and a LOT of Canon glass. I'm not complaining or leaving Canon. But as an avid Canon user who is heavily financially invested (unlike some constant whiners on here), I have enough skin in the game to voice some dissatisfaction on rare occasions.
Again, this is all academic until we know what is/is not in this new machine. Just having fun debate for now
