'Dexter' Stalks Sixth Season Renewal

This won't surprise anybody: Showtime is getting ready to announce a renewal for Dexter.

The show just had its second highest ratings ever on Sunday night, delivering 2.5 million viewers, up 43% from the fifth season premiere.

That almost certainly means the upcoming finale on Dec. 12 is going to set a new viewership record.

In 2008, Showtime confidently renewed Dexter for two seasons. That's not likely to happen this time, since key talent deals will need to be renegotiated before the show's seventh season. Expect the offical Dexter renewal within the next week or so.
