Found this article, saying -
"(Venom2 post credits scene) & Coupled with a recently circulated photo of Hardy wearing a logo hat for the MCU movie, it does seem to be confirmed that
Venom will appear in Spider-Man: No Way Home.
https://screenrant.com/venom-spider...,Venom will appear in Spider-Man: No Way Home.
"Based on the image of Hardy in a
Spider-Man: No Way Home hat, which were likely given to those who worked on the movie, and the
Venom: Let There Be Carnage post-credits scene, there's a fair amount of evidence that Venom will be in the Spidey movie. But how exactly he'll fit into the film remains to be seen. The
Spider-Man: No Way Home trailer confirmed characters from other universes will be part of the movie's story, with Peter facing off against Doc Ock, but it's unclear if Venom could be another villain or an ally of sorts. Since there are a host of
villains either confirmed or rumored to be in Spider-Man: No Way Home - including Willem Dafoe's Green Goblin and Jamie Foxx's Electro among others - Peter could no doubt use some help. Of course, there are also reports of Tobey Maguire and Andrew Garfield returning as Spider-Man, though the later has vehemently denied his involvement."
"It's also possible that with so many characters already either rumored or confirmed for the film, Venom won't have a big role at all. He may instead appear in a cameo role, perhaps setting up a proper Spider-Man vs. Venom fight in a future movie. Considering how highly anticipated a meeting of Spider-Man and Venom is, especially after the lackluster reception of Raimi's
Spider-Man 3, it might be best to save that conflict for a movie of its own. Still, with
Venom now in the MCU and Spider-Man: No Way Home including characters from various universes, it seems almost certain Hardy will show up in the movie as his next appearance after
Venom: Let There Be Carnage."
I call this a unconfirmed confirmation.
Because if Venom ISN'T in No Way Home, WTF was that post-credits scene about?
