That isn't Hasbro's fault.
No, but it is what it is. The reason the Jumbo GG figures sell at $80 a pop is almost entirely because of their nostalgic appeal. A figure of Hayden Christensen in the same style does exactly nothing for us.
I don't blame Hasbro for trying, but this was a non-starter. Even different than 3.75" figures on vintage style cards (because there are still a lot of diehard 3.75" collectors out there regardless of which films they're from).
Maybe not to the OT generation, but I think you'll find it has plenty of nostalgic appeal to the PT generation. And they're the future!
When the PT generation is even close to being as inspired by those movies as the OT was, then we can talk about the power of nostalgic appeal. Right now, it's not even close.
