That's design art, JT. All the figures go thru the design/costing/approval stage before they can be included in the poll. They also check for things like likeness rights. It would be incredibly stupid to include charecters in the poll, that can't be made if they won. Due to cost, Lucas/LFL giving the charecter a thumbs down, or likeness rights. The Tonnika Sisters, ring any bells?
Like Tycho also said at one point, one of the Hasbro sculptors actually sculpts figures for his own collection. So the early appearance of Duros, doesn't mean he had the fix going for him. They may have done sculpts for all the charecters in the polls, who knows. Just because somthing turns up fast, doesn't automatically point to a internal fix. If so, you think they would have put the fix in for the Imperial Dignitary. The figure that all the Hasbro folks at Cel 2, said they thought would win.
