I always wanted 1.8x crop raw on a $800 extra (with battery) that adds an extra pound with (as Andrew says) wobbly hdmi cable. The 70ms RS is the icing on the cake! I know some of you say that you only care to shoot 1080p, that's great, in 2012-2018 maybe, but it's 2019! I can see a big difference even on my phone, when it recorded in 4k and playing in 1440p. TV's are also much bigger, not to mention 4K UST projectors are getting quite cheap and I have seen many people set those up now (120" + screen at 7" from wall).
I can see the appeal of raw, but I personally would rather just have 10-bit internal 4k with low RS and low to no crop. I would take that anyday over external raw on what I mentioned above. It will come in time and we might even see an R body within a year, that lacks the drawbacks. Raw on the eos r would be much more attractive, with low RS and crop. Thats why I feel they might actually do it, that addition won't threaten their segmentation of the C line; I can see them omitting 1080p from the raw, just like they did with the current 10-bit external to protect the c100 lol.
