Why would they need to mass slaughter Avengers so they can introduce others? All they would need to do is send some heroes off on solo adventures, explain that they were leaving for personal reasons, retiring, etc., just as in the comics. Killing off characters is short-sighted, especially when they have so much potential.
The idea that Marvel would kill off Iron Man (or any of the Big Four) is particularly strange. Tony Stark is Marvel's most successful solo hero and starred in the highest-grossing solo superhero film. They're not going to kill that golden goose off. Not only would Disney fire everyone who tried it, but there is no precedent in canon for it. There is also no need. Feige has already said that Marvel will recast the role instead of rebooting it, and that they don't see their franchises as finite trilogies. Fans may want Stark's blood for whatever bizarre reason but they're not going to get it.
