I meannnnn there's been sooo many hints, or at least I'd like to think so.
The Spidey Tracker used to promote the movie is basically identical to Insomniac's Spider-Man games - https://spideytracker.net/
Zendaya's method dressing on almost every red carpet has been all black
Peter confirmed to get organic webbing!
Sadie Sink rumoured to be playing Jean Grey??
And every bit of setup points to Secret Wars, especially after that new Doomsday trailer.
Tom Holland's Spider-Man is getting the symbiote. I'm calling it now.
Or maybe that's just the spidey sense talking.
