I'd like to try doing some video at some point but those kind of limitations are fine for me considering the relatively portability of the camera.
Yeah I wouldn't expect heat issues during stills, though my K-5 overheats in live view... and I imagine the Sony may too.
The thing is that the A7R II might be an option for serious filmmaking, so there overheating would be an issue. Of course, being _that_ cheap compared to the cameras you would otherwise have to buy, you can just buy 2 of them and alternate. What I don't understand is why the camera doesn't do line skipping (optionally) to reduce rolling shutter. If you move the camera a lot, rolling shutter is a problem, but moire and aliasing isn't (you wouldn't notice it through all the movement anyway), if you don't move the camera rolling shutter isn't a problem, but moire and aliasing is. Being able to chose would certainly help. In line skipping mode it wouldn't heat up as much.

The other measurements don't reveal anything concerning either. That there is noise reduction at the RAW level for extremely high ISO settings is not ideal but one can easily address that by not choosing such high ISO values.
As for the EOSHD review, I don't think this reviewer is unbiased. I'm not impressed by his style and wouldn't be surprised if future reviews would paint a different picture.
He is quite... well, Clarkson-ish, but I trust his judgment. He doesn't hold any punches. He's been using Canon as a punching bag for the past year or so. So I don't think he sticks to a brand because of bias. He works as a filmmaker, so I trust his judgment in terms of video more than reviewers that usually shoot stills and then try to test the video functionality of a camera... those tests tend to be pointless.
For stills shooters these things don't matter of course, and 30-45 mins of shooting (and it is hot in Berlin) is enough for most, unless they really buy this instead of a C100 II for example. A A7S with external recorder (or eventually a A7S II) seems like a better choice for those.
This is great for people who need to do either stills, or stills AND video. I could imagine a wedding photographer shooting with this Sony, occasionally doing video to give the videographer another angle.
But... I totally forgot about EVF... after all the sensor has to be active all the time while shooting. Maybe it does line skip then, leading to less heat?
What I don't understand is more heat in super 35 mode than in FF. They said FF uses pixel binning, so it has to read the whole sensor, do more processing... why does it heat up less?
