Neca has released the following information on their blog.
Now for some information that you did not know about. We are planning another collection of Cult Classics Hall of Fame for '07. We have 4 figures planned at present and 3 of the 4 differ quite a bit from their original release. We should be able to reveal the lineup at Toy Fair with images or at least details on them all. (Tentative Release - Fall)
Now for the long awaited Series 6 - yes these are coming. As mentioned earlier we have a lot on our plate in the first half of the year and offering some of the figures individually under the "Cult Classics Presents" banner allows us to release some great figures to you sooner since we don't have the time or resources to devote to an entire series or assortment right now. Cult Classics Presents will bring you Jareth, Hannibal (Version 2) and Reservoir Dogs in the first half of 2007. Not a bad lineup right?
Following up Series 5 (my personal favorite so far) is not easy but we have some great figures lined up for CC 6 including another highly requested license that has never received action figures before. We start sculpting some of these in mid January and we can't wait.
Also in development (not sure on where, when, or how we will release these yet) are 2 more figures from Dawn of the Dead, a 2nd and very different version of Jareth with Hoggle possibly as a Boxed Set, a collection of goblins from Labyrinth, and more.
