According to the DisneyParks blog, the Pirates of the Caribbean ride at Walt Disney World might have something from On Stranger Tides added to the ride. Here's what the article says:

This classic Disney attraction, which inspired a four-part film franchise, has undergone a few changes in recent years due to the success of these movies. First, Captain Jack Sparrow made his debut at the attraction, then Captain Barbossa (pictured above) appeared aboard a pirate ship. More recently, the ghostly apparitions of knaves Davy Jones and Blackbeard have materialized.

Our friends at Walt Disney Imagineering dropped us a line today to let us know that something from the most recent film, “Pirates of the Caribbean: On Stranger Tides,” is about to be added to the attraction here at Walt Disney World Resort. Can you guess what it is?

Updates to the attraction will be made overnight, so Pirates of the Caribbean will remain open to guests during park hours.

Here's a StitchKingdom article talking about DisneyPark's intriguing post:

In honor of International Talk Like a Pirate Day, the official Disney Parks blog has announced that Walt Disney Imagineering will soon be taking a cue from the latest Pirates of the Caribbean film franchise, On Stranger Tides, and adding a new feature to the attraction.

Speculation and rumors have run rampant for months that mermaids were intended to be added to the attraction at the Magic Kingdom and the announcement has now re-fueled it along with an off-again/on-again full day closure for the attraction scheduled for October 9.

The attraction has already shared an incestuous love affair with its namesake film, beginning with the addition of Captain Jack Sparrow and Barbossa and inclusion of Davy Jones and Blackbeard from the later films.

Of course it could also end up simply being the Black Pearl in a ship bottle, but the news has certainly sparked the interest of theme park fans. One thing is for certain: if mermaids there be, they probably won’t be of the same sort that once haunted the waters of the lagoon at Disneyland.

So tell me: what could this mean for the Pirates ride?
