I think it unlikely it will get a dvd release any time soon. After the initial streaming on Spike, it has been streamed on Amazon Prime and Netflix, but there has never been any (reliable) talk of it making its way on to disc.
Its possible that because it has been downloaded/screen capped so often that they realise it wouldn't make financial sense to go through the whole rigmarole of making hard copies, boxing them, producing covers, marketing, handling and shipping etc.
