When is the movie The Twilight Saga crossbreed coming out?

"Crossbreed" is not part of the Twilight Saga created by Stephenie Meyer. It is a fan fiction story about the future of Jacob and Renesmee, the daughter of Bella and Edward. There is a fan-created movie trailer for it as well. Their story was left open-ended in the books, and Stephenie Meyer has said that she could go back and write about them some day.
