I think Hot Toys will be interested in this series. Not only have they released every major "costume" character from the Nolan films in one way or another, they have even took the plunge into the 89 movie and vehicles from all the above. The 66 series allows them access to nearly the whole of Batman's Rogues Gallery, and a ton of vehicles. Imagine a 1/6th Hot Toys Barris Batmobile?
I'd love to see Retros of these as well. Unfortunately, Mattel will probably be involved and veto this. If BBP or EMCE could do it, I'd be more excited.
