Sorry, was referring to the RPG 6th ed.
Sprawl Gangers made a big noise then dissipated and passed unmentioned - like a fart in church.
Last I heard (a couple of years ago now) was that it was on hold because CGL found making miniatures too difficult???
I assume that was a convenient excuse as they just ignored any comments along the lines of "....I've got minis just get the rules out...." and put what ideas they did have into a crap card/boardgame instead.
