Saw 3 to Saw 4

Rating: Null/10 (6 November 2006)

Well, the question I have is did they end this movie as they thought this would be the last one? And now that it's doing so well they figure to make another one? I think it'll be a sequel with many flashbacks to john's past. I believe that Amanda is alive and that Jeff would get killed off in the first part of the film.
Other than that I'm at a loss of what else they can do without it looking like it's been done before in Saw.
How could Jigsaw be alive since he practically cut off his neck? They could always show that Amanda got shot in an area that doesn't completely end her life. Either way we know that the doctor is dead and that they kid will be alive.
Thoughts, anyone? Jon A>
