This just in from the fine folks at Scream Factory (via their Facebook page): Norman Bates and "Mother" are coming home to Blu-ray & DVD this fall in two Collector's Editions.
Both films feature the original Norman – played, of course, by the legendary Anthony Perkins – continuing the Bates saga over two decades after Alfred Hitchcock's immortal classic: Richard Franklin's excellent Psycho II (1983), and the 1986 follow-up Psycho III, which picks up almost immediately after part 2 left off, with Perkins in the director's chair as well.
Scream Factory have posted no other details as yet, but rest assured we'll keep you updated!
