Shit! Hulk ripped Wolverine in half!?
Did he regenerate it back?! 
those are the versions from the "ultimate" marvel universe, not the "real" versions or at least that's what it looks like to me. From what I know Wolverine's bones are laced with adamantium which is pretty much unbreakable (ultron who's made of adamantium has fought all of the avengers and just shrugs everything off cause he's made of adamantium...I just read an issue where he takes a shot right from thor's hammer and doesn't even flinch).....I don't think even the hulk is strong enough to break that stuff let alone rip it like that so either this version of wolverine doesn't have adamantium laced bones or this is just a promo pic for something....or this version of the hulk is stronger than the real marvel universe hulk....
yes...I am a comic book geek.
