As if you didn't know: Sony has had the Spider-Man film rights since way back in the day, and as Marvel was their own studio and is now owned by Disney, Spider-Man has never been a part of the Marvel Universe in films or television. At least not since he was web-slinging on The Electric Company.

I have to assume that a weak showing for The Amazing Spider-Man 2 and a critical smackdown on the sequel meant that Sony may have decided they'd prefer to share in the money-printing machine the Marvel folks have got going on over at Disney rather than just keep stamping their feet and insisting they know how to do this. (I think you can point to whatever went down on Spider-Man 3 vis-a-vis studio notes as the beginning of the problem).
