Personally, I think it will be the most recent Fett figure we have, painted white. When ESB was in production, they made the first Fett costume all white. There's ton's of photos of it. But they thought that his costume should be different than the Stormtroopers, so Joe Johnston HAND-PAINTED the costume, dings, dents and all, and the final Fett we know was created.
Very cool mail in.
