I think what really drove the price up was the base (which I think looks awesome) and the backdrop (could care less about that).
Say we are paying $30-$35 extra for the base and $10 for the backdrop. Without those two items this figure would be priced around $225. That would seem pretty standard, but still a little high.
I kinda compare him to General Zod, two sculpts that isn't a remake, Zod has a better base since it's dynamic. he doesn't have any accessories but his armor alone makes up for that and is only priced at $239.
