@xwraith: I think for it to be a "reboot" they'll need to delete character history and memories and reset timelines. If they do like DC does and turn the stories into "Iron Man and Captain America meeting for the first time to battle a new enemy - Doctor Octopus???" it would be a reboot. If Steve and Tony still remember their history, are conscious of the events of the past and are sitting there with Miles Morales going, "Wow, we've lost a bunch of friends and gained some new ones..." then it isn't really a reboot. Just a refresh.
