Honestly I think Marvel's out of creative ideas. This is probably the least original thing they've ever done. It's basically a big superhero war with a light sprinkle of retcon-tastic Jean teasing. It's nothing we haven't seen before, Marvel's just connecting their franchise in weird ways (Iron Fist's story to the Phoenix namely) which they have a weird habit of doing (it's like gross comicbook incest). I think they need to do some serious rethinking, but since this event is clearly selling they obviously won't.
