I think they should just go with the Multiverse Saga. Despite all of the Phase 4 projects we've had, I still don't really have a clear sense of where it's heading. We've seen mostly multiverse stuff, but we've also got cosmic stories (Thor, Marvels, Eternals), grounded stories (Hawkeye, TFATWS, Thunderbolts), and magic stories (Shang-Chi, Moon Knight, WandaVision, Doctor Strange) so I'm not sure what it will be, but my general consensus right now is the multiverse.

^I think they're mainly towards the Multiverse but also other stuff like young Avengers.

Aren’t phases 2 and 3 part of the infinity saga?

@Bruce Wayne of Earth-1 I completely forgot about Young Avengers. We have seen that as well.

Phase 2 and Most of Phase 3 to me is the "It's all Connected" Saga. in Phase 2 Most of the Movies you had to watch the netfix shows, Read the Tie-in Comics, and also Watch AOS/Agent Carter to make a lick of sense of what is going on espeically A.O.U.

If I were going to give the phases subtitles I would use.

Phase 1: Avengers Assembled (this phase is about the heroes being introduced)

Phase 2: Earth's Mightiest Heroes (this phase is about the world responding to the heroes)

Phase 3: Fall of the Avengers (this phase is about the heroes struggling to operate due to the pressure of world politics)

Phase 4: Legacy of the Avengers (this phase is about normal people being inspired by the heroes)
