The cyborg thing is nothing new: after all, in the finished film Darth Vader is a cyborg.
Like a construction base. Remember the thing has only recently been built. Think Endor in Return of the Jedi -- except that Alderaan is a major Imperial system rather than a foresty backwater.
I meant more normal looking cyborgs like with one metal arm and a human body. Vader sort of doesn't count.
Hmm. It sounds like alternate Star Wars is costing quite a bit more money with some of these special effect shots.
