The creator said this is actually the last one. "The Final Chapter" is in the title. Yes, I know horror movies has had titles like that and they kept going, but the creator of the series is very straight forward (when not releasing cryptic pictures to tease the fans) when he talks, so the fact that he's calling it really does say the series is coming to an end with the 4th installment. Personally, I'm a little bit iffy on this one because I thought the third game wrapped things up nicely.
