Sterling, there are plenty of these books on the market right now. In fact, horror has within the last year or so made itself a viable genre with smaller publishers again. That is one reason why I review many modern books in my fanzine, because I know that most "advanced" collectors are caught up in a back-issue vacuum, completely oblivious to the current comic market.
As for HoM, I haven't heard a peep about it coming back, but I don't think you can ever count that out. Frankly, I'm surprised DC/Vertigo hasn't leapt at the chance to cash in on the current popularity of horror comics, and Marvel as well. Marvel has released the Essential Tomb of Dracula and The Witches ( Dr. Strange type stuff), but they haven't delved into true anthology horror yet. As for Vertigo, I would have thought they would be all over it by now, but they are completely missing the boat. I'm very let down!
It would be cool to see HoM back, but i don't see DC/Vertigo and Marvel doing anything about it.
It just looks like IDW are going to rule the Horror section of comics in moderns
