Quoted from johngravenews:

Who knows if this is true or not. I can see both The Muppets and Toy Story doing well (although TS is old news now unless there is another version in the pipeline). POTC? Is there really still demand for this? I'm trying to remember what the last film was about and nothing springs to mind. Given there's already one game based on the theme I can't see there being the demand for another.
