According to Latino Review[RUMOR] , SONY is allowing Spider-man to join the Marvel Cinematic Universe. People often suggest taking Latino Review’s reports with a grain of salt but they’ve had a decent track record with respect to the MCU, accurately reporting on much of Phase 3.
With this recent report, it looks like Spidey will be making his grand appearance in the third Avengers film, currently being split into Infinity War Part I and Infinity War Part II. The story line will see some pretty bleak changes for the Avengers. Keep in mind that this movie will follow Captain America: Civil War and be warned, these are spoilers:
Thor is missing in action, imprisoned somehwere. Steve Rogers is dead. Chris Evans will not be in this movie. It makes sense when you see that Evans is only signed on for two more movies, and would leave room for Bucky to take up the sheild just as he did in the comics. Anyway, this prompts Spider-man to swing into action and join the fight.[/mks_highlight]
Again, it still might not be true but if it is, this is pretty exciting stuff.
