I'm confused by people's response to the Spiderman trailer.

Spoiler!

The multiverse was pretty much a given at this point was it not? The way they explained time travel in End Game, and the way the leveraged the Quantum Realm to travel through time was pretty much an intro to multiverse theory from the comics.

Plus Spider-Man Into The Multi-verse was such a success that you knew that was going to make it's way into the main MCU too.
