Unfortunately (?), from what I've heard, the re-releases are likely to be in resin. AFAIK, they did not get production moulds, but the masters, and went for resin moulds, most likely to cut back on material costs.
This will make the minis less attractive for gaming use, I'm afraid, and possibly more aimed at the collector. I probably won't be buying resin ones as I constantly had problems with limbs and weapons snapping off with the metal ones. That said, I guess it will boil down to price and availability.
