Quick theory I wanna throw out there before I see/hear someone else say it.
The Halloween episode coming up where they wear comic accurate costumes is going to start the process of true integration and acknowledgement of the comics into the MCU and vice versa, like a meta multi-media-verse lol. She is destroying the 4th wall (dimension) to the point where characters within the show are watching the show with us...
So yeah, besides it being cute, they're wearing their comic accurate costumes because Wanda's hex is creating a vacuum that is going to suck up all all of these 'dimensions' of the Marvel brand thus making them cannon, 'real' and reactive to everything hence forth.
I wouldn't be surprised if we get a Logan moment where there is some sort of exposition or reveal with Vision picking up one of the comics.....
They hit this landing right they can do fukking ANYTHING lol, I'm fully expecting Wade to show up in this show at some point.
What if that's the cameo they're talking about.....
Like yeah, surface logic leads to more X-men characters but that's almost too easy.
