Why would they "let it die"? Becuase they sell? Becuase it's got reusable tooling which can lower the cost and raise margins? If it/they did not sell they would not continue to make them.
But they don't sell, look how many armors from IM3 end up getting discounted. What I mean from "letting it die" is that there's too much potential for movies on the horizon to still be using IM3 as a source for new figures
