yes, the prequel... but there are two versions.
One was completed and the studio went ape shit and remade it, however the first one they shot was complete and they plan to release it on DVD at the same time. There are infact two versions of the 'same' movie
I think this is the first time this has ever happened

Apparantly the original one they made is supposed to be decent and different, the other is supposed to be a copy / tie-in with other exorcist movies, which gets me worried
