No DVD of horizion.
Several cancelled shows from the last few seasons or so have already been released on DVD including "Over There", "Conviction" and "Trial By Jury".
I have seen nothing about Heist coming to DVD. These seem like niche programs like Showtime's excellent "Brotherhood" that was released on DVD this past summer. I had not heard of it, but for twenty bucks of so I took a chance and loved it.
"Heist" much like "Boomtown" has episodes that no one has seen because the plug got pulled so quickly.
I'd love to get the show on DVD, but I doubt that I ever will. If I see it on TVShowsOnDVD.com or at the video store I;ll snap it right up. I'm not going to waste my time with a Google search every week.
