Is this for real or just made up?
 * Well, to quote Terry Rossio, there is little value to the early rumors and speculation. Though also said it was a lot of fun because of eager fans looking forward to further exploration of the PotC world. Now actually quoting...But alas, a film will happen, or not, based on too many factors, and it's guaranteed whatever gets distilled down into the press is speculation, spin, or too partial to be of value.

Meaning, I'd probably guarantee this should be considered a rumor, as with all news reports that don't come from Disney directly. Of course, some fans like to keep something in mind should a film start production, should it be true. With that said, I can only say what I usually say... wait for Disney or Bruckheimer. ;)
