Answer: A slim one. Ronald Moore told reporters last week that "the plan is to end the show to bring us to a definitive conclusion. There are no plans, or even thoughts in our heads, of doing a full-on feature or miniseries or anything beyond that. But it is the kind of thing where you never say never." Moore and David Eick also confirmed that they've approached Lucy Lawless newly sprung from ABC's passed-on remake of Footballers Wives about returning for the final season.
