OMG that clip is GOLDEN. And Patrick Stewart's thoughts re: Charles/Hank seem to be requited by Nicholas Hoult, too. :)

Re: Rogue, well, since Magneto is at full power it's a safe bet that that small hint in the chessboard scene at the end of s3 was indeed the first stirring of the "cure" losing its effectiveness and everyone's powers, including Rogue's, coming back. So I'm assuming she had a scene with the team in the future, perhaps using everyone's powers to fight the sentinels until one of them got her.

re: Charles, older Charles shouldn't be in his Patrick Stewart shaped body, but in whoever played the comatose guy, and who wants that? I am so not sorry that timeline just got wiped out, let me tell you. Thank you, Mystique.
