But it's very possible that it is Atlantis. I posted this in the "Plot Ideas for Pirates 5" blog post but here it is:

1. After Jack angers Blackbeard in his cabin, Blackbeard carves into the voodoo doll a symbol of a trident which appears on Jack cause the doll is connected to him.

2. Blackbeard's sword is called "Sword of Triton" and was made in Atlantis and has 1/3 jewels of Triton. Triton in greek mythology is son of Poseidon, god of the seas, and like his father, he wields a trident.

I think "The Sword of Triton" originally wielded all 3 jewels before Blackbeard somehow got his hands on it and I think that the power of all 3 jewels of Triton when replaced in the sword can unleash the power that is needed to get The Black Pearl to it's right size. And since Barbossa is the new master of the sword, he will return.

And the writing on the blade might possibly be helpful to locate Atlantis.
