Specifically, the three brother robots, Fire Convoy, God Magnus, or the like. Any of the completely new Takara molds.
What I want to know is whether or not they (the Japanese versions) have a Hasbro copyright on them. (Optimus'/Fire Convoy's is on the underside of the siren battery pack).
Just trying to figure out how early (or late) in the design process Hasbro has to say "We want that!".
I don't have any of them, but I know that they were created in Japan before the Hasbro\takara contract and are thus manufactured and designed solely by takara.
Hasbro imported the toys and made minor adjustments.
Check BWTF for more details on the individual toys.
