The age of video drones

I think that in film making, most crane-shots, as well as most helicopter shots, will very soon be replaced by remote-controlled-drone shots. It's much cheaper, and much more flexible, the small drones can go so many places cranes or choppers can't.
See examples here, notice especially the third video, play it full screen.

With which other method would you like to have your
camera sweep right in front of a rushing train?

Of course, as with anything else exciting happening ever, there is already talk about outlawing drone photography. God forbid any of them should catch us picking our nose.
