Don Mancini offers little on CHUCKY 7, except, "...can't say anything yet!"
Now, if a movie wasn't going to happen, then I'd see no reason for any person(s) involved to remain tight-lipped. But Mancini is doing that. Which pretty much confirms that he is busy working on a story for CHUCKY 7.
Where should the ever-evolving story of Chucky go after the events of CURSE OF CHUCKY?
