Some very, very exciting news!  This just came out an hour ago.  Supernatural has FINALLY been picked up for US second run syndication.  The really exciting news is it will be running on TNT, which is owned by Time Warner, corporate parent of Warner Brothers which owns Supernatural.  So not only are they keeping the show in the family, but this is the best possible cable network for Supernatural to land on.  TNT is a strong network (stronger than The CW in my opinion) and its target audience is far more suited for the show.  Attached is the press release from The Futon Critic.
