Ducky Does TV has posted the Warner Bros. TV Comic-Con Schedule which includes Fringe. According to Ducky's schedule, Fringe is scheduled Saturday, July 26th, 4:45 p.m. - 5:45 p.m. Saturday is sold out by the way.
What does all this mean? To be honest, I can't exactly say. My only experience with Comic-Con was feverishly refreshing last years live bloggers who were covering the Paramount/Abrams/Cloverfield panel. So my best guess is there will be a panel comprised of Fringe writers and/or directors and/or producers and/or stars who may have something to say, or show, or could just be there to look pretty and field a few questions about the show.
