The video blogs had a pretty meh reaction to to it so I'm still hoping, but I think Canon is too stuck in it's new old ways to get it, sad to say, so I'm probably kidding myself. It's surely the bean counters and MBA types making a mess of it all and not the engineers.
I mean they did finally get it enough to add 1 series AF to 5 series and boost to a full 6fps and all so they improved and they did get much of it right, but was it because they got it or because they were still just laying back and only reacting when they had to? Had they not, if you think about it, the D800 woulda made the 5D3 look silly. The fact they still muddled up some video features and autoiso (and by muddled i basically mean crippled for ridiculous reasons) you do wonder. And the fact they thought they could just let the low iso sensor performance sit there in the same spot for a full half decade now makes you wonder too. They did get the basic body specs pretty sweet finally at least, for whatever reason.
The message got thru to Canon, and they opened a dedicated support facility in Hollywood, and are in the process of trotting out cinema bodies and lenses.
It was probably unrealistic to expect Canon to turn a 5D MK III into a 4K cinema body with XLR jacks, etc. but some actually thought it would happen and were disappointed. Its a still body that does video and they are obviously going to differentiate it from higher end video bodies.
Thats a pretty standard marketing scheme, but its also a practical one. Some want a stills body with video, and some want a all out video body that can also do stills.
