No, I dunno what happened with Jigsaw, all I know is that the original leak said "Saw: Legacy" (and Murdy's accidental leaked photo said "Saw: Legacy" too, lol) but as we know, both here and Orlando, Jigsaw was only represented by a room at the end. The assumption went that the producers wanted to avoid spoilers (the trailers were very vague and didn't give away any of the, err, "money shots") and they just said "use the one trap in the marketing, please."
Yeah, I'm actually really liking the look of the new film. It's pretty obvious that they're saving some stuff; there's a big two story house in the countryside where Michael kills an old guy that could make an appearance. It's obvious there's stuff we're not seeing, and I'm excited. Maybe instead of Michael's house, the new facade could be Smith's Grove? Unless that gets shot down due to the Asylum controversy too...
