I only saw two endings, but they implied many others. If Magneto gets his powers back, then so should Mystique and many others -- everyone. If Xavier could survive, then so could Cyclops and Jean Grey. Cyclops because we never saw him die on screen. Later Jean says something to Logan like "Kill me before I kill again." Everyone is assuming that that is a confession about Scott -- but, she also had "killed" Charles by that time. Who can say what she meant?
I am trying to recall the situation with the Brotherhood of Mutants. Magneto founded the group, but I was sure that Destiny and Mystique took control of the group when the new X-Men group was formed. By "new" I mean when Nightcrawler, Wolverine, Storm, Collossus, Thunderbird, and so on joined the comic. Magneto did not lead the Brotherhood anymore after that period, IIRC. IMO, that makes the split onscreen between Mystique and Magneto make perfect sense (although, I hated how they did it).

magneto is more powerful that mystique and the others so maybe that's why he is getting his powers back
Maybe, but I think that the permanent cure was not permanent. It may be one of those cures that requires constant application of the dosage of the curing formula. But, even Hank McKoy said that the drug inhibits or suppresses the mutant gene... not essentially a cure. Just like Stryker's control drug, the cure is temporary and must be reapplied. At least, that is my opinion...

didn't hank say permanently in the mansion?
He said permanently suppress... But, he never clarified that. He was not the expert on the cure. He only knew what was being reported to him and what he saw. But, look at it again. When Hank met Proteus (the kid in the white room at the lab), Hank goes to touch him and his hand reverts to normal. When he withdrew his hand, it returned to being blue-fur covered. I think that by implication the cure must be applied on a regular basis much like insulin for a diabetic patient.
Leech's powers are only temporary, as they saind in the movie, so I assume that cure wasn't completely finished. They had to use it to fight the Brotherhood, obviously it would keep them down long enough to be taken into custody or something.
Magento probably got his powers back because he was very powerful and his powers rely on something that is all around the earth at all times I guess. I assume that lesser powered characters will get their powers back over a longer period of time. 😖
