Here's how it should have been:
Jameson (as Sony): It's all my fault. I drove the Spider-Man franchise to it's grave.
Executive: That last movie was the only one that could have allowed us to keep the rights.
Sony: Yes. Spider-Man was a great franchise. I just couldn't see it...
(Marvel-Sony deal in the background happens)
Sony: It was... A ruse! A trick! Marvel stole my franchise! (Note says "Courtesy of Marvel Studios) It's a menace to all other studios! I want that money-making studio prosecuted! I want it drowned by it's own pool of money! I WANT SPIDER-MAN BACK!
(Newspaper shows Marvel having Spider-Man back)
(Spider-Man begins swinging around the city, with Iron Man and Thor flying in the background while Hulk leaps around from other buildings)
