You make really great points but it turns out I still think the 5D Mark III is the best camera for the job. I'm not a fan of the super shallow DoF all the time as well but if I'm honest, other cameras wouldn't help much in that regard either.
Let's say I get a GH4. Awesome, now I can 4K, much better sharpness than a 5D. But to compensate the awful crop factor and terrible noise performance I get some wide lens (like the Sigma 17-35mm f/1.8) and a Speedboster. Now I'm stuck shooting at f/1.2 and having extra glass from the SB just to deal with the crop factor and noise.
I'll have to sell my Fuji to buy the new camera. One of the reasons for that is because the Fuji isn't cutting it anymore for stills. I think the A7S would be in the same department.
I think the 5D Mark III is the only good video camera out there that can realistically shoot great stills as well. Not to mention they're easy to sell and having Canon lenses/accesories is still a smart choice in this field.
I'm a bit aprehensive about the RAW's limitations but in the end the problem is just storage (cards get cheaper every year, I can buy two 128GB cards right now and have almost an hour of available content) and one extra step in the editing process, which is transcoding the MLV raw to CinemaDNG or whatever.
I also watched some videos that really indicated that the 5D's RAW has considerably more dynamic range than a GH4 in the flat profile. It's hard to beat the 5D's 14-step DR.
