User blog comment:J Fan/Pirates 5 has a release date!/@comment-3106883-20130116002152/@comment-1984959-20130116010535

^I wouldn't know about how the other films were announced. As of right now, the only Pirates I really followed since day 1 was OST - started following around 2008 when it was a mere rumor - thanks to the power of the internet.

As for Depp, according to some news articles, his only other film-related projects is Transcendence, which I think is going to start production in the next few months(depending if said news is accurate). As far as I know, anything else he's working on is either cancelled or delayed. And given that Bruckheimer doesn't have any known projects after Lone Ranger, it is possible that they might start work on P5. Plenty of time, if you ask me...if comparing to Depp working on The Tourist before working on OST back in 2010.

Not sure if they have everything planned out or not, though I somehow think they are in the planning stages now(probably as one of those "set things now, plan later" kind of ideas). But all I can say it that I hope they keep this date, considering how often some release dates tend to change somewhat.
