[NOTE: Updated August 26, 2013. SyfyMovies tweeted: "Because too much is never enough, we're doing an all-day Sharkathon again on Labor day - featuring #GhostShark @ 7pm and #Sharknado @ 9pm!" - If that is airing on September 2, that may mean a portion, or all, of the Stargate Atlantis marathon may be CANCELLED (again). I've sent a tweet asking for clarification. Gosh darn it... Addendum: However, Syfy ran a promo commercial for the marathon on Aug 26, so maybe there's still hope. Updated August 27, 2013 I was wrong, no hope. Stargate Atlantis marathon CANCELLED (again!) in favor of another Sharkathon. ARGH!]
