I read a rumor that she would be seen at one of the celebrations at the end of the movie. So, it sounds like she may not die in the next movie.
If Lucas keeps all of this up, he may have to title the whole series, "Attack of The Groans".
He could be leaking this to stop the assumptions about what will happen in 3.
She could die, but then come back as a hologram-the first showdown between Darth /Anakin and Obi Wan (Ewan McGregor) is gonna be sweet in Ep. 3!
