Yeah this sequel has been rumored for awhile. Pinhead was in the Hellraiser movies, never liked them. Bruce Campbell(Ash from Evil Dead movies) has also been rumored as third character in movie. IMO Myers is the best choice seeing as how when people think of horror movie characters they think of Jason, Freddy, and Myers.
BTW You might not have seen it but the last post on that site says that the plans for making the movie are dead in the water at the moment.
