When asked during the 2013 Winter Press Tour about the future of the serial-killer thriller, Nevins promised that there was "a clear endgame in place; I just can't talk about it just yet. The decision of when to end Dexter is ultimately a creative decision and will be made on creative reasons."

Looking past Dexter's demise, Moonves also took the opportunity to tout Showtime's next big offering, Ray Donovan, starring Liev Schreiber.

Dexter returns for its eighth season on June 30, its first-ever summer premiere.
