An actor kicking the bucket doesn?t necessarily mean future figures won?t exist, eg Carrie Fisher. An actor being fired for whatever beliefs pretty much means that character is dead and buried never to see the life of day anymore, hence no more figures.
There is now a limited amount of Cara Dune figures, because no more are being made. Limited supply = increase in value. I say just wait for the whole thing to blow over. She was a shelf warmer prior to sacking, the hoarders I imagine are going to end up with a lot of dust collectors.
