I found this article which pretty much confirms my suspicions: https://www.theguardian.com/science/the-lay-scientist/2016/feb/25/how-real-is-that-atlas-robot-boston-dynamics-video.
Anyway...
This pretty much sums up the current situation:
These videos are more press release than research paper, designed to show the subject in the best possible light. I doubt we’ll see Atlas running cross-country races any time soon, and there are a whole host of limitations, from battery life to noisiness, which would need to be overcome for success in the wild, or even a warehouse. Still, if you’re in any doubt as to what its creators have accomplished, or how hard this is to do, I’ll leave you with a compilation of some of its peers.
This one is pretty good too!
