Controversial opinion here, but I have very little interest seeing Sony-verse Venom fight MCU Spider-Man. At this point there's no logical reason for that to happen: Venom's origin is completely dis-associated with anything Spider-Man, and on top of that he's ALREADY being portrayed as an anti-hero, which didn't happen in the comics until long after Brock came to grips with his Spider-Man hatred.
I'd be far more interested to see them trend in a direction more akin to the more recent Venom stuff in the Cates/Stegman run....particularly some of the mythology around the Absolute Carnage/King in Black stuff.
There's a line in the first Venom flick where the symbiote talks about "being more." Let's see that pay off.
