I think Marvel is trying to hide what is going on and many speculate Andrew has been lying saying he isn't in it just as of a few days ago. I think the other two webslingers are in it. If they are are not though? It's going to be a huge disappointment and missed opportunity. On the same scale as not putting Leia, Han and Luke all on the screen at the same time together for Star Wars IMO.this is basically SPIDERMAN: ENDGAME with every Spiderman joining forces to defeat Sandman, Goblin, Electro, Doc Ock and and The Lizard. I wouldn't put it past them to throw Venom in there as well to basically have a Sinister Six showdown without calling it the Sinister Six.
and I'm totally fine with that. Super curious to see how they weave all these worlds together.
In terms of Venom, based on the End Credit scene from the last film, it completely fits. That's the first thing I thought of after seeing that scene.
