don't think the purpose of this robot is to replace vehicles with wheels
or tracks...I think it is being designed to carry some of the burden
that your typical "grunt" has to haul around these days. So think more
pack mule, or litter carrier, etc.

It's certainly clever. The way it recovers its balance is certainly  
impressive. So far though, it doesn't demonstrate any compelling  
argument for legs over wheels or caterpillar tracks. None of the  
terrain that the video shows the robot crossing would present much of  
a challenge to an all-wheel-drive vehicle. Look at these loonies:
