Hate to break up this drug induced Spiderman circle jerk ..... but Kevin Feige in a recent interview with the French website "Reviewer.fr" put all this nonsense to rest ....
Firstly, for instance, Feige confirms that there was a conversation about inserting Oscorp Tower into Joss Whedon's The Avengers film, which would have crossed the Spider-Man cinematic world (which is owned by Sony) with what Marvel is up to. Feige said in the end though that "the deal was never close to happening".
He also confirmed that there are no plans to bring Spider-Man into a future Marvel film. »
