$99.99 -- assuming the helmet can't come off. They'll definitely crack the $100 mark once you can remove his helmet. The ANH version is relatively non-complicated. Also, the likeness is easier to do than if the sculptor had to match facial features, even scarred up ones.
As soon as I hear, I'll let you know, but I'm guessing at $99.99. Sideshow know if they go above $100, it takes them to close to the other 1/6th figures, and they don't want to go there!!
