Azazel must die but in a third prequel. Angel Salvadore and Riptide too
Emma must just leave at the end of the third one, she understand she was in the wrong side. So, if they make an X4, they can justify her come back, like Singer wanted for his X3. And yes, in a third one they can show Magneto recruit Sabretooth and Toad.
