Re: 'Paranormal Activity 3' Gets 2011 Release Date!
Yes the third film was designed to be a prequel and show the origin of the entity how it attached it's self to the sisters in the first place and connects to the second one and ultimately the first. I've been expecting a fourth one to wrap up the first story line. There have been fan suggestions that they could just continue this as a franchise since it continues to make money each year.
