No time given or details of the number of titles and quantities. It all adds to the suspense, really hope it lives up to the expectation, I am sure it will, especially if it is the POA set.
They specified that it was a "project" so if there are misc. titles, they must be connected on some level.
Specifically, they wrote "Project completed and in the plant right now! It will be announced in our Christmas batch." So the project is part of the batch, but the batch is not exclusively the project.
