Is this an alternate AoA or the original when it first started? Because there are a lot of characters shown there dead in the AoA universe.
Maybe all the "old" events getting teased are alternate universes where Civil War never ended, Thanos was successful with the Infinity Gauntlet, DoFP carried on and became Years of Future Past, Planet Hulk being either one where Hulk didn't return or did and "won", Armor Wars were Tony didn't stop it etc etc.
I'm thinking they all tie into Secret Wars, but maybe some are part of the multiverse incursions (so the ultimate one).
