If you look at the name change list, you’ll see things like The Green Hornet changed to The Green Hornet (in 3D) which is clearly not going to be the official title. The Night Chronicles is a production banner and the film’s art hasn’t ever included the words The Night Chronicles on it. All of the evidence points to the fact that the film was always intended to be titled Devil, just as the second film is titled Twelve Strangers. After all, Night is using the banner to work with new up-and-comers and help them to perhaps get their work out to more people.
It does show confidence in the work that is being done on these films, however, to not include that as part of the title. The final official release date of Devil is September 17, 2010.

In unrelated news: Box Office Mojo also reports that “James Cameron Presents Sanctum (3D)” has been renamed to drop any reference to James Cameron. It’s now simply “Sanctum (3D).” One wouldn’t be going out on a limb to say this might be because AVATAR was a box office failure.
