I find this whole lost/destroyed/stolen mold thing to be quite interesting. I don't know how much it would cost to build new molds, but surely it would be profitable to reissue the 5 G1 dinobots? I would imagine that these would be snapped up faster then they could roll off the production line... regardless of RRP!
But part of me also likes the fact that the G1 Dinos will never be remade. All that exist in the world right now, will be all that will ever exist. (As owner of all 5, is that elitist of me?) Kind of makes them a bit special. IMHO.

Mind you, I would really like to own a G1 Mirage again...
