CNN has a cool video (ignore the ad) of an experimental exoskeleton being developed by Sarcos in the states. In it, the demonstrator lifts hundreds of pounds of weights with the harness, while remaining nimble enough to catch a bouncing soccer ball and even dance. The one glaring drawback is that it's tethered, and appears to be powered via the tether. This is cheating a bit, being able to power an exoskeleton like this is one of the major hurdles to its development. Still, it doesn't seem to be ripping the guy's limbs off everytime I tries to do anything, which is a positive step towards power armour.
