Ok, I just finished watching the Ratner, Penn, and Kinberg commentary on the movie and the deleted scenes and I have to say, they should've included about 6 of the 10 scenes and used 2 of the 3 alternate endings. The ending where Rogue doesn't take the cure and where Beast stays at the school to teach made much more sense and even both writers said it did in the commentary.
Also, a HUGE explanation of the hidden ending and the guy in the coma is finally revealed. Though there isn't an extended shot of that scene, they did have more footage which was supposed to show the guys name so you could figure out what happens. The name was supposed to have said P. Xavier. Penn and Kinberg said that he is Xavier's twin brother who was still born (they make mention of Cassandra Nova and just say they made her a guy instead) and was kept alive for whatever reasons. So if they make an X4, we can still have an Xavier, but he can now walk, dunno about his powers though.
