i09 has the full story.
“So much happens in [the 3rd and 4th Avengers movies], as you can imagine, and so much is affected by it that we felt what better person to hold your hand and lead you into the next incarnation of the MCU, in a grounded, realistic manner, than Peter Parker?” Marvel Studios president Kevin Feige told io9. “So, coming out two months after Untitled Avengers, [that’s what] much of what the next Spider-Man film will be about.”
“I hope [the news comes] after that. I think there will be certain elements that start to come about, not the least of which is the already announced release date of the next Spider-Man film. But other than that we’re going to keep it very close to the vest because this is really about focusing on the unprecedented conclusion to a 22-movie overarching narrative.”
Can’t wait for the 7th!
