Yes, from what I understand, the Raimi trilogy, the Webb duology, and the Homecoming films will all make their way to Disney+. I love the Spider-man movies (Amazing Spider-man less) and am eager to have them all available on a single streaming service!
I am also very eager to see Homecoming 3, whatever it will be called. I usually steer clear of the movie rumor mill, but this one has me engrossed and excited!
