The Comic-Con panel for Saw 3D brought the debut of the trailer for the seventh and as announced final one in the series. The Saw franchise has made over $730 million worldwide and sold over 30 million DVDs, all the while being made on relatively low budgets making each one profitable despite some drops in box office take for the last few. There is understandable skepticism though, with many believing if Saw 3D is a hit that the studio will find an excuse to keep it going. The movie is slated to release on October 29th.
