I agree that normal sized characters (Magneto, Spider-man, Iron Man, Gambit) should be in the 2" scale. But for huge people like Juggernaut, Hulk or Strong Guy, I think 2.5 would be cool.
But on that note, I think people like Giant Man should be made Maximate style. I don't care if they're articulated or not. As long as they're sculpted with their arms in some sort of pose, them I'm fine. I don't need Giant Man to be in kneeling down or doing ballet style poses. I don't need the articulation for him. But that's just my opinion.
Also, I'm not really feeling the sculpted chest on apocalypse. Someone mentioned, it looks to much like a kubrick, and less like a minimate. I hope this isn't something that happens on the regular.
