And assuming that's the actual problem....it's all innuendo, rumor, and hearsay at the moment.
Still, Marvel's playing with house money so to speak. Avengers hit a billion BEFORE rentals, BR's and DVD's, etc. Damn near pays for all the other movies they've made at this point. None have posted a loss, so they're 10 figures+ in the black at this point. Can't see anyone screwing with such a monumental success as marvel's been since Iron Man. If they faltered, then I could see it, but otherwise it makes absolutely no sense at all.
