I just have to say I have been relieved to see that classic and cult releases have continued to be in DVD format. I actually haven't heard of any cult material being released in Blu Ray, though I think that Tim Lucas may have wrote a piece on his "Video Watchblog" a couple of months ago about a foreign Blue Ray (or digital high-definitiion DVD format?) release of Horror of Dracula that had mind-blowingly crisp definition. I have to confess that I am on the fence about digital restoration since it seems to "restore" vivid color schemes that were never seen in ANY previous generation of a classic film. On the other hand, they do look very pretty on the slightly more state-of-the-art playback equipment I acquired two years ago (mind you, I'm far from getting one of those giant rectangular gizmos suspended from the ceiling by designer kryptonite chains).
There was a report the other day about one of the big labels issuing the Cushing/Lee classic "The Gorgon" as part of a fourpack. The Paul Massie "Two Faces of Dr. Jekyll" (which features what I personally regard as one of Christopher Lee's better performances of the period) is also going to be in this new set.
I don't know whether it would be worth upgrading to something more finely-defined than the existing DVDs. Sometimes, the grain of the original video master gives the product a very raw look to my eyes, as it is.
