We’re here sweating our asses off at this year’s San Diego Comic Con trying to keep you guys posted on all of the major horror announcements… and here’s a whopper of one. B-D reporter Slice reports live from the event that Lionsgate will instantly begin prepping ‘Saw 4′ if the third film in the franchise is a sucess, which I’m sure it will be. We were also informed that if a fourth film happens, Tobin Bell will return as Jigsaw. Watch this spot for more news as it comes in live from the con!!! ‘Saw 3′ hits theaters this October.
