Wanted to clear up the above that I posted by posting the full comment Amy Pascal made, which is being omitted from most outlets.
“This is not the last movie that we are going to make with Marvel — [this is not] the last Spider-Man movie,” Pascal says. “We are getting ready to make the next Spider-Man movie with Tom Holland and Marvel, it just isn’t part of… we’re thinking of this as three films, and now we’re going to go onto the next three. This is not the last of our MCU movies.”
Most are leaving out the part where she says "it just isn't part of...", which seems to be her catching herself slipping up. She clearly says this isn't the last MCU movie, but based on comments Feige has made in the past about Spider-Man being able to hope between Cinematic Universes and now this, it has me wondering what exactly she was going to say.
It's possible she was catching herself on a spoiler from NWH. What I am assuming will happen is that the new trilogy won't be exclusive to the MCU, meaning it will be a shared trilogy between the Sony Spider-verse and the MCU. And we should finally see a live-action adult Spider-man story, which is great.
