Third sequel?

Rating: Null/10 (26 November 2005)

I don't know if this is true or not, but I was watching Fox News last week and I only caught the tail end of this, but supposively there is going to be a third sequel to "Meet The Parents". Is this true? Has anyone else heard about this, and if so, what will it be about? I think it would be neat to see Greg and Pam married with a new baby on the way. I can only imagine what that would be like.
Another thing, in the original movie, Greg says he grew up in Detroit, yet when the Byrnes' go to meet his parents, they are living in Florida. I would assume they may have moved there to enjoy retirement, but then we see Greg's nanny in Florida too, which means he must have grown up there. I'm confused...could Greg have lied in the first movie and said he grew up in Detroit when he really grew up in Florida? Any ideas?
