Yes, there is talk that there's a fourth and fifth planned in the Saw series, man these films keep going up and down (see what I did there?). The star of the films, Tobin Bell has admitted that he's signed up for both these films, and confirmation comes in the form of rumours that multiple writers are already working on the fourth film.

From Bloody Disgusting and quoted from JoBlo:

Tobin Bell's apparently been saying that he's signed on for both SAW IV and SAW V with the folks over at Bloody Disgusting revealing that there's already multiple writers working on story arcs for a fourth and possibly fifth installment.

Okay, I do believe they could carry this one off, but they have to keep it fresh, and by that I do not mean just throwing in new fiendish traps. They have to think of some unique hooks for why it all keeps going and what end game there might be. Of course you're talking to someone who hasn't even seen the second one yet...so what do I know. Could they pull this off for another two films?
