Haven't researched this much, soI apologize if this has already been fully addressed. I enjoy the base game and am hoping some expansions are planned for the near future.
Better yet... why doesn't Hasbro just license this for a full on G.I Joe game deck builder!
This has been mentioned in passing a few places but we do have expansions planed for the game. In conjunction with the upcoming launch of Freedom Squadron Role Playing game we plan on putting out some new cards based on characters from there. These cards will open to anyone to purchase and we hope it generates some cross interest and after that we will be looking at putting out the first expansion for the game.
As for the later question, that one I leave to the universe to answer :-)
