Dark Shadows Movie

I just heard that Johnny Depp is gonna be making a Dark Shadows movie. I've only seen a few episodes of the original series on DVD, but it was an interesting soap opera cum gothic horror. What's really exciting, though, is the rumour that Tim Burton will be directing. Not that I'm desperate for him to work with Depp again (they're overdue for a break) but it'd be cool to see Tim make a vampire movie. If a Dark Shadows movie is successful, can a Buffy the Vampire Slayer movie (a good one, this time) be far behind?
