Someone said this upcoming phase of the MCU is supposed be Strange/Wong heavy, I figure with the introduction of Egyptian Gods, Demons, and other entities, the final battle of the Phase 6 is gonna be lit. They'll be leading the charge like Tony into what I hear will be Secret Wars.
The world is expanding. We're going from cosmic to extradimensional levels. Hopefully, F4/XMen/Inhumans will still be a thing. I need to see Negative Zone, Phoenix, Doom Galactus Now that the watcher is canon, I wonder when we'll see things like the abstracts and the living tribunal. I assume GOTG/Thor will cover the cosmic side of things, Strange will be dealing with the multiverse, and Wanda and Moon Knight will be introducing to the spiritual stuff.
Was America gonna drop Wanda into Hell? Or was that Mustafar? Marvel: What If showed Vader's castle, IIRC. If that was Hell, maybe we'll get Mephisto.
Strange mentioned Spider-man, so he knows that he cast a spell to save the multiverse, he just wiped his memory of Peter Parker. Anonymous Spider-Man dynamics with other characters will be a riot.
