the entire big dog thing is pretty "old" already but the refinements look awesome.
projects to make real walking robots and exoskeletons are making great steps the last couple of years. I've been to a seminar about "human engineering" and the advances in making things like force actuated exoskeletons, the kind that allow wheelchair bound people to walk again, at affordable prices is certainly something I kind wait to see getting introduced for public used. Cyborgs ftw.
certainly a great example of what current age robotics and control engineering can accomplish
