I think just by going on past trends of TV related books, Grimm just came out and might do well for the short term. I'm sure the show has a cultish following that might not know the comic exists yet. Buy now for a discount and sell maybe for $10 in a week or two if they dry up-regular cvrs. that is. X-Files is also dropping in about a month. I preordered some, and am hoping it draws out older, hard core fans, that have to have it. Who knows though, only the market decides these things.
I am interested in X-Files simply because I am an old X-Files junkie from way back. Hopefully there are more of me out there so my book can be worth something because I will be trying out the first storyline.
Also, a book like this could be testing the waters for new movies, so there is a long term possibility for this series. They are always talking about a new X-files movie possibly being in the works so it could happen. They might just have to do it with new leads. As long as its not Robert Patrick, I might be O.K. with that.
