Notably, these videos were made by essentially amateurs. Even if the shooters are industry pros, they're still taking these shots on their own without a film crew and a professional setup. Just running around with a "normal" camera you can carry in one hand.
I wonder if this is going to be a dead end now that Nikon has acquired RED. I have a sinking feeling that the product lines will be split again, and that the stills bodies will not get any new video features, which will be relegated to dedicated video cameras.
[1] Something I've heard is that perceived video quality is more strongly correlated to the data rate than pixel resolution. These cameras can record at about 6,000 Mbps which is in the same league a "large format" and IMAX style cine cameras.
