Scooby Doo: The Mystery Begins hasn't even aired yet, but that's not stopping WB from planning a sequel. In a recent interview with MovieHole.net. Robbie Amell{Fred} says a sequel is already being talked about.
"“There’s a second script”, that would serve as a sequel, says Amell. “In the first film, we save our first mystery – but by the end of the mystery we’ve destroyed a lot of stuff. The next one would be set at a Lake Resort – a Summer Camp kind-of setting – where we’re forced to work to pay off the damage we made in the first film.

Scooby Doo! The Mystery Begins premeires on Cartoon Network on September 13th and will be released on DVD and Blu-Ray September 22nd.
