This worries me a lot. Am I the only person in the world who wants an awesome hybrid camera? What I was hoping the 1DX would be. There's no headphones and no clean hdmi out. It's an awesome stills camera though. Then if you want more video features you have to jump (if you stay with canon) to the C300 which can't take a great photograph.
I don't want a cheap 4k concept camera. I want a $12-$13k sick HYBRID DSLR that does everything we know canon is capable of doing at this price range. I work in some extreme environments and my clients include Red Bull; I'm not usually in a position to have two bodies, or even two photographers, in some locations because sometimes you get the shot by pure magic. With Canon EVERY SHOOT HAS BECOME A COMPROMISE.
So I was rather hoping the concept camera would be the top of their hybrid line. From many comments here I'd say I might be wrong, or that the date has nothing to do with the physical camera but a film. Maybe canon won't make this camera because my segment is too small. I think it's because they sell pro video gear too.
I have four busted 5D mkiis and have to reinvest right now. (I also have a broken 5D underwater housing) The timing is very interesting for me right now. RIGHT NOW the best hybrid camera appears, to me, to be the Nikon D4. And part of me is suspicious that Nikon have decided that because they don't produce video cameras at all, they aren't going to hold back.
I've pre-ordered two D4s and some glass and will see how that fares.
DISCLAIMER: (1) I am not trying to start some sort of Nikon / Canon war here. I am really just expressing my frustration at what might seem to be a unique situation (not IMO at least). I am VERY interested to hear from others in a similar situation. (2) My studio does a lot of commercial work too an we've enjoyed the relatively high bit rate on the Canon 5D mkii despite the moire etc. see our work at www.jtography.com
I'm only entertaining Nikon because we'll use the atoms ninjas on safer sets and in studio for clean hdmi - Something I felt that canon out to have offered us right now. Oh and I'm looking forward to sharing the live view on clients' iPads on set too. I felt that was a neat way of circumnavigating the small screen issues of DSLRs. ...there were a lot of factors.
I agree about people having to compromise, the 5D/7D can really be a pain in the ass on shoots. But at the same time, I just don't see a way that they could make a top notch still and top notch video camera in one and keep it at a reasonable price. There will always be people that only want a camera for stills and only want it for video, and those people would end up paying for features that they just don't want/need/use. It would be cool, but I think at this level people buying the cameras are professionals for the most part, and most pros either shoot photo or video, but not both. And plus, from a business standpoint it's better for people to have to buy two bodies than 1. But if you want the best of both worlds, and are willing to spend $12-$13k, just buy a 1DX (or 5DIII) and the CDSLR, problem solved.
As for it being a "cheap 4k concept camera," a camera is only a concept until it's released, so I don't get what you mean by that. But I think the fact that it's being released under the Cinema EOS line says it all, I don't think it will be a particularly special camera in terms of stills. It's a video camera, and the first DSLR that Canon will be releasing that's truly video-oriented... It's about damn time.
