Well, there's the raptorial legs, for running, but I can't really think of anything else specific off the top of my head. Full cyborgs are probably what they're thinking of, but they're unstable and crazy expensive.
What I thought was interesting, is that cyberware is actually kind of outdated and nano/bio/gene 'ware is where it's at these days.
Also, a lot of the functions that used to be cyberware only actually have AR/Comlink options, like the electronic senses or smartlinks.
On the other hand, they could just be mech fetishists. Into the whole full body replacement (torso, skull, limbs).
