Nah, there is going to be a Superior Spider-Man
AU crossover issue, do it's definitely Otto.
As for it being an alternate reality, or more likely a reality that will be reset by the end of the story, I assumed that as soon as I heard the name of the story. "Age of Apokolips", "Age of X", "Age of Ultron". All alternate reality re-sets.
However, there is already some slight continuity disconnect swith Thor being dead. In the Avengers arc where Bendis set all of this up, it was continuing from the Avengers Next
animated movie, in which we met Thor's daughter, and found out that Thor is still alive in Asgard. And Emma's mental powers are no longer on the fritz for some reason.
