I think in that bottom pic, it is a room of some abusive, rapist dude's secret room full of pictures with the women he raped that he took those pics of for some reason. Maybe this man will be in one of Jigsaw's games. I have a feeling the new Jigsaw may be Dr. Gordon, not Jill, you can obviously see she isn't happy with John's crazed work in one of the previous pics. As for the top pic, it is in fact Eric Matthews, not Dr. Gordon, cuz Dr. Gordon has lighter hair than that and he would be wearing a prosthetic leg not a leg brace. And one question i asked myself today is how long is the gap between SAW III and SAW IV, cuz Eric has long hair and a beard which could indicate that much time has passed. That part confuses me most. We'll just have to see this month, October 26th. For once it is finally October, we are that much closer.
