In a landmark move that comic fans have been waiting/wishing for (for over a decade) today it has been announced that Sony Pictures is bringing Spiderman into the Marvel Cinematic Universe.
The basics are as follows;
Spiderman will first appear in an as yet unnamed Marvel movie in the MCU.
Sony will then release the 3rd installment of their Spidey franchise on July 28, 2017 but it will be overseen by Marvel Studios President Kevin Feige and his team. To quote the official Marvel press release
“Together, they will collaborate on a new creative direction for the web slinger. Sony Pictures will continue to finance, distribute, own and have final creative control of the Spider-Man films.”
