It's not like fans didn't have that twist figured out over a year in advance anyway.
But seriously, back on track, I would like it if the Mandarin is shown mainly as a non-physical threat for 95% of the movie, and then at the last moment, he is shown to have devastating powers from his rings. It would be a cool twist, and I know that Shane Black talked about really wanting to explore reversals and incorporate twists and turns for this movie.
