It seems like a part of the pirate theme is a hidden treasure, with X specifically marking the spot. Considering Epic's penchant for hiding hints about major events and world changes within the actual game, there may actually be hidden treasure players have to find.
Previous season themes have included things like superheroes, a snowy fantasy Christmas, darkness rising, and much more. What I'd really like to see as a part of a pirate theme is ship battling, but that's probably a bridge way too far for an existing battle royale game, but imagine how much fun would be building a boat out of nowhere.
