As expected, TNT has renewed Dallas for a third season. No final decision on veteran Southland and freshman Monday Mornings, but neither is expected to be renewed. TNT will likely make the end of the two dramas official in the next two weeks as the cable network is gearing for its May 15 upfront presentation. Also likely coming up in the next week or so are the new TNT series pickups, with the Howard Gordon-produced Legends and Michael Bay-produced The Last Ship expected to get a nod. Produced by Warner Horizon Television, Dallas is a follow-up of the iconic 1980s series. TNT has ordered 15 episodes for the third season, which is slated to launch in early 2014. “Although we said goodbye to Larry Hagman and his iconic character J.R. Ewing this year, Dallas has many more stories left to tell, and the Ewing clan will continue to honor J.R.’s memory by keeping its audience surprised and delighted,” TNT’s head of programming Michael Wright said.
