Well Sony has few franchises right now. They lost the Bond franchise and won't get anything from next years Bond film. They miss-judged what Jumanji would do and seem prepared to make it a franchise now going forward. Ghostbusters III is their newest attempt at trying to create a new era franchise there. So they don't have many franchises left to build around unlike Spider-Man.
But bad press was KILLING Sony the past couple weeks. They went from one guy claiming how he was gonna make a ton of spin-off tv shows that no one is demanding to wanting to remake the Princess Bride (which many call it fucking garbage already). The press was not helping and had this idiot shut his mouth and didn't say a word it may have not kept coming up.
I can already predict by 2021 , Sony/Marvel will extend the deal for Holland to keep him around.
