I think its more like two more sequels.

I heard they were making two more.

*points to the above comments*

What they said. :-P

*points to comments too* Last thing I heard was that they're filming two sequels, and at the same time. I'm such a pathetic Johnny Depp fangirl..... :D

And may I also point out that they used the "Providence" in the filming of at least one of them? I saw her sail back into port from the hospital window.
