just throwing this out there
since Disney now owns marvel and all of its IP's, its logical to assume the publishing rights to the spiderman movies and everthing assiciated with it, including the rights to use the old spiderman font, would also be bought by disney.
unless there is still an existing contract between sony and marval that disney chose to honor (which i dont see why they would) that says XX number of spiderman movies must be made, I dont think we will be seeing any more spiderman movies made by sony studios
s this the explanation? probably not. but a theory nonetheless that could explain the rebranding
