"PC" may release later than planned...

According to a report by Walden Media's CEO (Cary Granat), the release of Prince Caspian has likely been bumped to a Christmas 2008 release, rather than Christmas 2007, because of the large amount of special effects that have to be done. According to this article and this report, it looks like it will more likely be released earlier than Christmastime, in the Summer of 2008.

However, they have also stated that they will be filming Prince Caspian, Voyage of the Dawn Treader, and The Silver Chair in order as a trilogy of sorts. Following will be The Magician's Nephew, The Horse and His Boy, and The Last Battle.
