Saw this over on Reddit and it's a really good point, hopefully Disney/Marvel can use this as leverage:
"Marvel - or their dad, Disney - still has one massive piece of leverage left in this situation: Spider-Man PS4.
Sony/Insomniac doesn’t own the video game rights to Spider-Man, they’re licensed from Marvel. Spider-Man PS4 is one of Sony’s highest grossing games ever.
I would not be surprised at all if Marvel now turns around and refuses to renew said license for a sequel in light of this development. In doing so, that then means Sony Pictures’ decision doesn’t just affect themselves, but also Sony Interactive.
Remember how the initial deal between Sony Pictures and Marvel Studios was established in 2015? By the CEO of Sony as a whole stepping in and basically forcing Pascal, Arad, et al, to do it. And if their actions now start to have an affect on Sony’s most profitable division, their video games, I would not be surprised to see the CEO step in once more."
