I frequently check Stephanie Meyers website and others that pertain to the Twilight Saga and I haven't heard anything about her finishing it. I did recently read an interview with her and they asked about it and she said she has no intentions of ever finishing it. It is kinda a shame because I read the first 12 chapters that she published on her website after that whole ordeal and it really did give a great incite to Edwards mind. You should check her site out if you havent already she has deleted chapters from the previous four books and short stories written from other characters points of view.
