I doubt Anna Paquin will be back for anything larger than a cameo given that she just gave birth to twins a couple months ago and has another season of True Blood to start filming.
Since the cast of the film is likely going to be massive, I don't think she will have much screentime compare to old&youngProfessor X, old&youngMagneto and Wolverine. I think there's an easy way for Anna Paquin to shoot her scenes in just weeks and they could use a double stunt if she is going to be in a lot of scenes.
