At the end of the movie when magneto was playin chess wit himself he tried to use his hand to move the little chess piece and the last thing it showed before the movie ended was one of the chess pieces shake a little when he put is hand next to it... so maybe he still has his powers.. and maybe leading up to another xmen movie??
for the people who has watched the movie already.. when jean used her powers like to the xtreme.. and her face turns all black... lol doesn't it look like a zombie from a horror film?? lol it looks so freaky.
