Mythbuster misfortune

It was really disappointing to see the end of the current season of Mythbusters.  The season have felt too short of late but that's not the reason.  Tacked on to the end of the episode was an announcement that Kari Byron, Grant Imahara, and Tory Belleci will not be back next season.  That wasn't expected, and the way they handled it was particularly ham-handed.  You might think, if they knew this was coming, that the show might dedicate a significant portion of their season finale to a retrospective on all the work the trio did for Mythbusters.  My current pet theory is that Discovery channel tried to get the three of them to do a fake Shark Week documentary, they refused, and Discovery lashed out like a petulant child and fired them all.  Probably not true, but it sounds good.  You can see the sad ending to season 11 of Mythbusters here.
