That's the rumor. I don't think it's confirmed yet. I figure if it doesn't happen, we'll have an extended edition changing the curse back to the way it originally was. (It would make sense, though, we had a "save "Elizabeth" and a "save Jack" movie, as well as an "everyone runs around the Caribbean looking for each other" movie...why not add a "save Will" movie to the mix? I wish they'd just left it as "Elizabeth was waiting for Will and the curse was broken and Jack and Barbossa spent the next 40 years stealing The Black Pearl from each other.)
