GUNN DROPS OUT
Back in the beginning of August James Gunn put up a statement regarding Scooby Doo 3 and Dawn of the Dead 2... He says 'People are writing in and asking me about DAWN OF THE DEAD 2 (or whatever it will be called), and SCOOBY-DOO 3. I've had discussions about writing both films, but I'm not going to do either, at least for the time being'.
