Although it should be a while off before Magneto breaks free, do you think we'll see him at his trial being sentenced to death and stuff? And this new method of the death sentence that uses no metal that Xavier said was being thought about? That'd be a cool way for him to break free, round about this time, whether it be him being busted out by the likes of Juggernaut or The Brotherhood, or some other way. Jus a thought.
I think we HAVE to see Hydra ultimatized! And in the pages of The Ultimates, too. They were formed to combat terrorism, after all, and so far we haven't seen that yet (Ultimate War doesn't really count, as they fought The X-Men in that rather than The Brotherhood), unless you would count a rampaging hulk and an alien race as Terrorists, but I would count them more as a rampaging hulk and an alien race.
