when is the next Pirates.. movie releasing?

hmm..the only OFFICIAL annoucement is that according to Terry Rossio (co-screenwriter for the first 3) is that Johny Depp IS returning as Capt Jack Sparrow. http://www.comingsoon.net/news/movienews.php?id=49716 there have apprantly been rumors running rampant about lots of other stuff lol. i guess Kiera Knightley has said no...and even though there are rumors of Sacha Cohen and Tim Burton..neither of those are true either. http://www.beyondhollywood.com/pirates-writer-calls-bullsh*t-on-pirates-4-rumors/ (fix the i in the link cant cause of mylot ) most of of the websites i found (including IMDB which just had the title and date) show a release date of either 2011 or 2012. so either way there is a wee bit of time before it comes out. i dont even think it has started production for that matter. even though i love the Pirates movies, im not sure if they should push a fourth one without more of the main cast members. i agree that Depp is the big draw, but he isnt the entirety of it lol!
