I may be new to this site, but on this topic, I have something to say.
1) While I have been resistant to 'fleshies', I will be happily awaiting this theme. So much potential for Fantasy and Historical. I can even see customizing possibilities for Sci-Fi themes if they do the crew of the Dutchman.
2) I wouldn't worry about the classic Lego Pirates theme. Lego recently placed Pharaoh's Quest on its products page. From the advance images I have seen (long since taken down by LEGO), it is a reworking of the Adventurers theme (with a tie in to Atlantis). Indy didn't kill it. Depending on the run of the Liscence, it may be some time before the classic Pirates theme returns (maybe with a new name), but I am sure it will. I would even hazard to speculate that POTC might improve the quality of a following Pirates theme, i.e. better weapons, more accurate ships, hair pieces.
I remain positive and hopeful.
