Maybe if Marvel was planning on wrapping up the Ultimate Universe entirely, but short of that I can't see it happening.
Nightcrawler, Jean Grey, Gwen Stacy, Peter Parker, Professor X, Mar-Vell, Richard Rider- Bring Them Back!!!
Come to think of it, isn't the Ultimate Universe becoming 616 what led to Ultimatum?
I liked this idea better when it was about Mike Morales.
Wake me when Peter is brought back to Ultimate Universe and Miles was a weird dream Osborn planted using Mysterio tech or something.
