Nationa Treasure 3?

I wonder when National Treasure 3 is starting to film. It's about time I think when the second movie came out for five years ago.

I love both of the movies even thou I think the second is much better than the first one. Maybe because of the filming locations in the Black Hills in South Dakota:).

About the third movie I hope it will start very soon and here on IMDB it has a portal that say that the third one is coming 2014.

About the story I hope that it will continue in the direction as the first two with something about Americas history and so on. I hope it will be non sci-fi *beep* because that would have absolutely destroyed the plot.

Nick, John, Helen, Diana and Justin must be in the third one also because they are all terrific specially Justin and John
