Any idea when Prince Caspian will be closing down? We're C. S. Lewis fans and had looked forward to seeing the exhibit. (I know, I know, we're the only 7 people in the US interested in it.)

Actually, I had hoped they would updated it because of the release of
Voyage of the Dawn Treader. But I guess not!
Anyway, anybody know when PC will close?

Well the reason it has not shut down nor updated is because shortly after the release of
Prince Caspian, Walden Media, which is a film production company that deals mostly with book adaptions, got in a tussle with Disney. They claimed they wanted more money from
The Lion, the Witch, and the Wardrobe though that deal was long done, and they were complaining about the summer release of
Caspian, which had to compete against blockbuster giants like
The Dark Knight and
Indiana Jones and the Kingdom of the Crystal Skull. A comprise was never made, so Disney broke off from it's deal with Walden Media. Unlike many of Disney's films though, Disney had no rights to the character, story, and actor likenesses, they simply had the distribution and marketing rights to those films, so Walden Media was able to turn around and go with another distribution company to make the remaining Narnia films, in this case 20th century Fox, with the same actors and many of the same crew.
So, since Fox is making the next Narnia films, Disney can't update it, but since Disney owns the rights to the first two Narnia films, they can still show
Prince Caspian footage indefinitely. So the simple answer to you're question is there are no currently announced plans to replace it, but I would bet it would be soon.
