Bravo announced today that it was renewing popular cooking competition show Top Chef for a seventh season, which will premiere in 2010. (No city has been chosen for the season, although casting calls will start on Oct. 18.) And after Showtime’s Californication launched its third season last week to the series’ highest ratings ever (up 57% from the season 2 premiere), Showtime announced today it had picked up the David Duchovny show for a 12-episode fourth season in 2010.
