If iMovie has been completely rewritten, it is clear that they did not take into account compatibility with third-party plug-ins. Apple ought to indicate such incompatibility on the iMovie webpage to better inform their customers. Let's hope that Slick can quickly port their plug-ins to iMovie '08, and that Cupertino will help them to speed-up the process.
