The Sony leaks keep on rolling, as we actually have some Marvel talk now the focus. A Brazilian website Overtice (via CBM) is claiming they've found emails detailing exchanges between The Russo Brothers and Sony's Amy Pascal. The emails have the directors confirm they will indeed direct Avengers: Infinity War. They are also offering to produce new Spider-Man films, and mentioning a tough conversation with current producers Avi Arad and Matt Tolmach being "worth having". This makes sense since it's was their film Civil War that Marvel was trying get Spider-Man included.
A reply was never given by Pascal, but this is the first piece of development ideas that have been released concerning new movies. We know that Marvel has invested a lot into the Russos, having them mastermind the vision of the future of Phase Three. Winter Soldier proved they can handle huge sprawling superhero filmmaking, which has led to their hiring for major Marvel events like Civil War and Infinity War. Having them involved as producers with this new Spider-Man universe could work, as Kevin Feige's participation won't like have enough time to help.
This might also help support the idea that Spider-Man could have a real role in Avengers: Infinity War. Keep in mind we might need a second source to have dug up these emails, since this site isn't really known to us. A cool option that both Marvel and Sony should consider at that summit in January.
