Jack Sparrow himself appeared at the D23 to reveal the date and official title for his next adventure announcing a Summer 2011 release date for 'Pirates of the Caribbean: On Stranger Tides'.
The good folks over at comingsoon.net believe that this refers to author Tim Powers novel 'On Stranger Tides' which tells the tale of a Puppeteer John Chandagnac, who was sailing to Jamaica to get revenge on the uncle who had stolen his father's inheritance, has no choice but to join the buccaneers who have taken him prisoner--and soon, known now as the pirate Jack Shandy, he finds himself learning to survive in a treacherous new world of cutlass-fights, sea-battles, and voodoo magic on sun-blinded tropical islands.
The legendary Blackbeard is assembling a ruthless navy of pirates living and undead to voyage to the fabled Fountain of Youth, and Jack Shandy must use magic, swordsmanship, and even his puppeteer skills to free himself and the girl he has fallen in love with from Blackbeard's deadly supernatural domination.
If this is the case it is a brilliant way to continue the Pirates of the Caribbean films, as in the last film both Barbossa (Geoffrey Rush) and Jack Sparrow set off to look for the Fountain of Youth. Could Black Bread be a torn in both there sides?
