The new series will give writers the freedom to develop characters, locations, and storylines without concern that viewers will guess or have expectations for certain plot lines based on what has already happened in the "Walking Dead" graphic novel series.
The new series could be set in a different time frame, several years down the road (in a post-post-apocalyptic world?); or maybe it'll be a prequel, with specifics on how the zombified world came to be. Maybe, a la "World War Z," it will tell the survival stories of various groups of people, from various parts of the country/world?
