On the wikipedia article about the IH it's said that the Abomination gets imprisoned in the Vault Abomination check the Film section, is this canon or has it been officialized by Marvel?
Eh, no, they're not. Madman isn't nearly the same as Abomination, even his powers are different. He's the only one of Hulk's villains that can alter his size and density, and make himself even larger than Hulk, Abomination is stuck in his gamma form. Not to mention that Sterns is a scientist, Blonsky has always been a soldier. Blonsky from the comics accidentally becomes the Abomination, and hates being the Abomination for the most part. Phil Sterns had been studying the Hulk since he was born, and loved having power similar to him.
I'm not trying to sound harsh, but I suggest you do some major research before making comments like that again.
