I still think that there's a good chance for a release of the Invisible Man & Creature sets in September or October. If nothing happens by then, I'll probably give up hope.
Whenever they release The Invisible Man and Creature From The Black Lagoon Blu-ray sets, I'd guess they'll also put them out together with the Dracula, Frankenstein, Mummy and Wolf Man sets. Creepy box may or may not happen. :)
