I think it's a bit of both. Some seem to be just retooled, others seem to be new molds. The water moccasin has some new looks on hatches, more foot pegs, etc. The HISS foot pegs are smaller to fit the smaller diameter holes. However it's confusing too b/c for instance the HISS doesn't allow a HISS Driver to fit nicely with the holdster, nor does the water moccassin allow copperhead to fit nicely. The copperhead that came with the thing does fit snuggly, but i'm talking about the one that came with the comic pack, b/c in my mind that's the original copperhead color... those greens. The original water mocassin has copperhead in those green/limegreen colors, so to me the comic pack copperhead represents what copperhead really looks like. Not the python patrol colors.
