At the D23 Expo in Los Angeles this weekend, Disney is regaling journalists and fans with scoops about their upcoming projects as well as looks at memorabila from the old ones. They've also used the opportunity to announce the official title for one of the most anticipated movies they have coming out, the fourth Pirates of the Caribbean film.

So the fourth film, going into production soon, will be called Pirates of the Caribbean 4: On Stranger Tides. What on earth that means, we probably won't find out until more production details come to life. But Pirates fans can chew on that for now, and decide for themselves if it fits in with the Pirates 4 plot details scoop we got over two years ago.

In more minor Disney news, the official title for the Jason Segel-Nicholas Stoller Muppets movie appears to be The Cheapest Muppets Movie Ever Made. I like the tongue-in-cheek humor that suggests, but are they really not giving Segel a Henson-sized budget? For shame!

UPDATE: Disney also sent us the official title treatment, which you can see below.
