Immortus also foretells that Wendell has some big stuff planned for him in the future. Hopefully not at the end of some Bendis story but a DnA one.
Ultimate Spider-Man #159, this makes me think Peter won't really die:
His identity gets out there publicly, so he's got to go underground or get a new alias.
Booster Gold #45, very good issue, Booster does some pretty smart stuff in order to find out what happened to the world....
He sits down at a computer and looks it all up on the internet. It's really smart thinking instead of flying around trying to find answers. And Doomsday in the world is actually being controlled mentally by an old Captain Atom, wowza!
That chick seems to have some powers too, but it's vague enough I don't know who her father was.
