I however, disagree. Because, Yellowjacket and Swordsman seem to break through the barrier; and what would be the point of bringing them back in Chaos War #5, if something wasn't going to be done with them?
Even in the Alpha Flight interview just recently - said that a mortal Herc tried to put it back together. So there's no doubt that he missed things. For example, people on the living side of Earth may have easily survived.
I just can't see why they wouldn't have just died in Dead Avengers, like the X-Men did in Dead X-Men - there'd be no point in bringing them into Chaos War #5 on the "living side" if something wasn't going to be done with them?
