I'm suprised this hasn't been mentioned here yet, but in April, Shout Factory will begin releasing some Roger Corman (produced) titles:
PIRANHA (1978) Both Two Disc DVD & Blu-Ray Versions
HUMANOIDS FROM THE DEEP (1980) DVD Only (YES!!!)
UP FROM THE DEPTH (1979) + DEMON OF PARADISE (1987) DVD Only
This is great news and the potential of titles for 2010 is going to be great. I know Cliff had a hand in this, so I like to give out a big thanks to him.
