I'm not excited about the $160 price, but it seems about right given the complexities of getting this figure right and the added bonus of the base. IG-88 and Grievous are also exceptions because of the complexities involved there.
Personally, I don't think we'll see all Star Wars releases up in this range permanently since Gree and Bly are still in the $120-$130 range.
However, the days of under $100 figures are limited, if not over, primarily because SSC has been looking to take on more and more complex projects which most fans have been excited about and wanting.
What I'm personally most curious about is what is going to happen with the humanoid characters given the recent HT collaboration announcement. Is SSC done making humanoids with this partnership now?
