According to @elmayimbe from Latino-Review, it seems the deal between Sony and Marvel Studios has come to a close regarding the future of Spider-Man.
Speculation has been going on for a while that he may be rebooted and brought into the Marvel Cinematic Universe, due to some leaked emails from the infamous Sony Hack of last year. Some emails stated that the Russo brothers were interested in producing a Spider-Man trilogy and that talks have started between Marvel Studios and Sony Entertainment to cooperate on the next film. It seemed as if Marvel Studios would share the rights with Sony Entertainment, but the character would become a part of their shared universe. Some rumors are unsure regarding the future casting, as some suggest that Andrew Garfield won't be returning as the titular character and they are considering recasting the part.
Now, it seems that a deal has been made that the character will appear in the upcoming Avengers: Infinity Wars two-parter, but further details are still unknown. There are further speculations regarding what characters will be featured in that film alongside the character and it is unsure if the rumored 2016 solo film will happen.
Still, take this information with a grain of salt, as there has been no official press release regarding this situation. The following source also includes some heavy rumors and spoilers regarding the upcoming films Captain America: Civil War, Doctor Strange, Black Panther and Thor: Ragnarok, so take this under consideration as you read the source.
