The phrase "Wind and Tide"' was used multiple times. At least twice by Blackbeard, once by Philip, and at the end by Angelica.

I think they're either referring to the On Stranger ''Tides' or paying homage to the book, or hinting at the next movie.

Who knows.

Also, I'm expecting them to be filming POTC 5 next summer. : P
