I think that Sideshow is slowly moving their prices up, inch by inch, since they see the returns for Hot Toys, Medicom and other brand figures going well for so much. I'd hate it, as I love the days of $35 figures, but times, they are a changin'!
The other brand's Superman Returns is now going for huge amounts, and technically, Sideshow could easily make him, as he doesn't require armor.
I think any figure that requires extensive armor, and other such details, will bring in a $100 neighborhood type of price whatever it is.
When a 1/6 Vader, or Vaders, as there are several of course, are indeed released by Sideshow in those AWESOME Lords of the Sith boxes, then the brethren will skip lunches and trips to the gas station to get one. Plus, he's got to be in the pipeline sooner than later (as would be Boba Fett I would think) as both have less armored bits. Helmets, yes, but less armor, so they are emminently more produceable by Sideshow. And that is cool. No dissing SS.
So, would I pay more for them than the usual? Maybe, maybe not. If they really had some pull, some extra extra something, yes. I would. Even with my own custom 77 one, I would buy their's too.
It comes down to this...
I don't collect PF. So, of course I want these in 1/6.
But, there is a Vader PF, and he's cool. So, do I want one? Yes. That may be the only PF I have ever wanted. But, would I pass him up for some 1/6 Elite ones? Sure. That's my scale. And, I bet I am not the only one that collects just 1/6.
Whatever they do, to be honest, I wish them well on it, and I hope it's soon.
I think that an "Elite" format would indeed make such figures as an Origins Kurgan and others much more of a financial possibility than the way it stands now. I think Sideshow needs such a format to release some things that they so far haven't been able to. It's just pragmatics.
