Warning: Spoiler information below. If you haven't seen the movie, I wouldn't look, but it's to answer Steve's question:
Alright, after the credits stopped rolling, you find out Charles is still alive. Well...you hear his voice actually. You see, if you remember, he was showing the students a video of a man without a consciousness, and he began talking to them about when it would be right for the psychics to use an opportunity like this. Well, guess what he did before Phoenix disintegrated his body. Quick transfer, and AH, that man has a consciousness now. However, I must have my Patrick Stewart in my movies whole, so in the next X-Men, he better get plastic surgery or something.
