How much money do you think Disney will be willing to give to Sony based on that if? And will that be enough for Sony to let them use Spider-Man?
It'd be different if Disney wasn't doing much better than Sony. But as is, Disney's in a position to logically give Sony peanuts for use of Spidey, and Sony wouldn't go for that.
