Hopefully the Gotterdammerung is in the works, though a creative (well paided person with spare money) could mode an existing reseen Thunderbolt mini to look like it. But i'd like have actual thing.
I know it's not on 3145 theme of this thread, but I'd hope more primitives are coming too, like from the recent XTRO: Primitves vol 3 and 4. I'd like to have one those Swordman (aka a Shadowhawk in disguise) Rifleman, Griffin.
