A few months ago, we brought word of the Powered Jacket MK3 by Sagawa Electronics, a fully functioning robot suit valued at around US$125k. It was undeniably cool and even came with a funny promotional video, but I think I could take it in a fight, which is rarely a good sign as far as mecha exoskeletons go.
However, work is currently underway to produce its successor, the MK4. Although still in development it appears to be getting some upgrades in size and intimidation.
