I know Shout Factory is soon going to be releasing Middleman on DVD, a fairly recent show. I'm sure sales for it will do quite nicely. Another recent show I think would be perfect for Shout Factory is Journeyman. It aired on NBC (Although 20th Century FOX does own the rights) and the most likely reason it hasn't come out yet is because of all the music in it.
I know Shout Factory has done well with series that used lots of music before (Freaks and Geeks being the best example) and this series is even shorter than that (13 episodes) so I think it would be very doable. I know their are quite a number of fans out there (Their was a large campaign to save the show) so I know many would buy it.
