The 'Fiege is too busy for Spiderman' doesn't quite make sense, unless Sony's has a vision for what they want Spidey to do that doesn't jibe with Kevin and the MCU's roadmap and they aren't budging on meshing the two. Most likely this is about money, and both sides will try and save face/pass the buck in the coming weeks.

But to have Spidey in 5 movies and set him up as an integral part of the MCU post Stark creates a huge mess for both sides that nobody wants, nor would be as profitable. Would the fans rather see Peter Parker interact with Tom Hardy or Sam Jackson and co? To see Sony (and to a degree Marvel) write Spidey out of the MCU and into his own thing is just courting disaster. And if they have to recast Holland to make it work, I refuse to see it.

I think a new deal gets done at some point. Too much money to be made and Spidey is too important an IP to screw up again. If not...
