Ryder will be in a new show called "Chasing UFO's" in the National Geographic Channel, or NatGeo if you will. Details about the show, premiering June 29th, is HERE including an awesome promotional photo of Ryder with her cast mates on that show. Please note that this doesn't mean "DT" is over - these two shows shot at different times of the year before they were put into post production.
Josh will be at the Through the Veil event the weekend of June 8th. Go to Appearances for more details.
In past news - "DT" returns July 10th on Syfy (only for USA Syfy customers), Josh is on a new Syfy show called "Insane or Inspired" Friday nights (some footage of him on it is HERE and HERE), Kara W. was the winner of the Air Date Guessing Contest, and there will be "DT" Marathons on May 30th 8:30 a.m. EST - 6:30 p.m. EST, June 5th8 a.m. - 5 p.m. EST, June 26th 8 a.m. EST - I assume 5 p.m. or later, since the schedule cuts off half way.
