The Future of Vampire Fiction

Well, I am gearing up for my panels at ArmadilloCon 2008 this August 15-17, 2008 in Austin. One of my panels is on Vampire fiction–Where has it been, what’s hot right now, where is it going from here? I’ve been doing a lot of research, a lot of reading and rereading, because I like to be very well prepared when it comes to these panels, but I also realize the benefits of consulting the communal mind when it comes to such a broad topic as this. What about it folks? Tell me what you think about vampire fiction. What does the genre need to do to stay fresh?
