The rather cool but disappointingly light teaser trailer for Saw IV has arrived online and it's giving away next to nothing. I have to say that I was hoping for some more from the teaser, but it does show that there's a lot of style in the film, and more to come from Saw himself.

There's not really that much we know about the latest Saw film, but I'm quite happy to leave it that way, I want the surprises of seeing Jigsaw's traps and what he has in store for whoever.

So without further ado, here's the trailer from Yahoo Movies [Flash:QT:480p:720p:1080p]. Teaser it most certainly is!
