I watched the video yesterday and even though there is still a lot of work to be done on the robots, it's amazing to see what they have already achieved!
The "all-electric" system is a huge deal, and a huge advance over BigDog (who you can see as Spot's less nimble older brother in the hill climb). No exhaust, no gas or liquid to balance, no fuel lines, fewer moving parts, less weight, rechargeable everywhere.
