Saw 5?????

I love the Saw movies (not because theyre sickening and gory and all that) I also thought it was a brilliant idea to bring out Saw 2,3, and 4. I even heard that Saw 5 is comming out on Oct 24 08 directed by another director and not Darren. I also heard that Jeff's daughter gets saved by Hoffman. Anyways, why do people think that the Saw series shouldve ended at the first one, or the 2nd or 3rd? For the first one, we wouldve never known what happened with Adam or Dr. Gordon. For the 2nd, we wouldve never known what was going to happen to Eric Matthews and what Amanda is going to do. For the 3rd, we wouldve never known that Amanda was being tested the whole time. All the Saw movies has great endings that you couldve never expected so the director has a point in making another Saw movie. What do you guys think about Saw 5? I really wanna see it because I wanna know what happens to Hoffman, Jeff's daughter, Jill, Det Rigg, and Det. Stratham (or how ever you spell it.) I cant wait
