If HT prices at $700-$800 that would be fine considering it'll be plastic. If it were diecast (which I'd prefer) then $900-$1K would be okay. I'm also guessing Sideshow will do a 1:4 maquette.
I like the pose of the Dragon figure but the Hot Toys version will be the one for me, maybe the King Arts one too if I can find a retailer in Europe that plans on selling their figures.
