Maybe four PFs a year, one iconic character per film with no time for a full lineup from any single movie. The license is going to have to have breadth and not depth. It's not a Pirates line, so no time for multiple Jacks, Davy Jones or Barbossa. Just Sparrow and then on to the Rocketeer, Jack Skellington, Etc. They will have to touch on a film and then move along to the next one.
There is more potential for unfulfilled hopes in this line than any other, I'd say. More characters to choose from than Marvel, Star Wars, Lord of the Rings or G.I. Joe, with fans from all over the spectrum in wild disagreement over what pieces ought to be a priority.
