They don't need to copy AoA, as much as I liked the origional. They can still do a story with Apocalypse with huge ramifications, they just shouldn't take it in the same direction. I'd prefer for Ultimates to stray farther from 616 and not use the same general stories as I've read the origionals, and read the Ultimate series for something different from time to time. You can have Apoc make horsemen out of some powerful marvel hero's he never has before, ppl not just from the X-Men, and have him take over an entire city. If done right they can make an awesome event out of it, if they don't constantly screw his character up like they do in 616, do the whole ancient Egypt Pharroh thing, and he's remaking a city in his image and the Ultimates have to stop him. Make him more psychotic in the way of killing ppl without caring, and have him presumed dead at the end with big changes happening because of it (he can always come back in another storyline). That was it's a huge event, Apoc is left as a memory til his next arrival of being a major bad ass, and you didn't have to kill Xavier or do the whole alternate timeline thing to do it.
(well possibly, in the ultimates atleast, not in 616).
