It looks as if a couple of films will indeed by heading to DVD, in March both Hellraiser: Revelations and Children of the Corn: Genesis both opened in the Rave for a public screening. That was the last we heard of them, so we assumed that they were released in one theatre as a clause to keep the rights to the franchise. But, I guess they thought they could make a little money out of it.
Anyway Dimension Extreme has released some artwork for Hellraiser: Revelations, Children of the Corn: Genesis and The Zombie Diaries 2: World of the Dead which you can check out below.
At this time there is no release date for Hellraiser or The Zombie Diaries 2, but Amazon.com does have Children of the Corn: Genesis for pre-order which is set to be released on DVD on August 30, 2011 at $19.99 and Blu-ray for $24.99.
