Yup. In troper terms, Vampires have just about reached their peak decay level and are ready to begin their deconstruction cycle. This has already started to a degree- 30 Days of Night seemed like an example, though I didn't see it and can't be sure. The grues or whatever in Descent may also count.

Zombies are harder to do. They're a good idea, but one without much meat on it. You can only do so much. For me, though, the most interesting thing about a zombocalypse is the effect it has on human society. If I were to do a zombie story, it would be more about politics than revenants chewing on people. But, Max Brooks has covered most of that angle already as well.

If I may plug it so shamelessly, this page is based on my view of where vampires and such monsters are heading at the moment.
