'They' never said they are out of the question. A couple of people said that the setting is boring because it's been done a lot and that they would prefere to do other settings. But if the entire narrative team decides that's where the series should go next, then that's where it will go. No setting is out of the question; individual developers have their own opinions, though.

Besides, the Golden Age of Piracy setting has been done a lot too. I don't think their argumentation really applies anymore.
