Believe me, they have a lot more stashed away than a puppy dog. The next generation they are working on will actually look and sound like Schwarzenegger. Even will say "I'll be back" and "get to the chopper" and will have red glowing eyes. It's a bit scary.
Boston Dynamics has been doing humanoid robotics for some years and it's pretty damn good at it, I would have loved to have worked on some of their stuff.
