Yes, Iron Man 3 is going to be the one that takes the hit when the dust settles here and that is what Feige and the other filmakers intend to happen. Except that 1) nothing in the films makes it so that these three had to have happened at the same time and 2) nothing in the films makes it so that TIH and Thor could not have happened before the first Iron Man. In fact, the credits scene for Iron Man implies that they do take place before it. The only film conflicting with Homecoming is Iron Man 3. So far no one has been able to show me anything from in the films that show why Iron Man, Iron Man 2 and The Avengers couldn't have happened all in the same year. All I've heard so far is that there is six months between the first and second confirmed by dialogue. That leaves up to six months between Iron Man 2 and The Avengers where they could still fit in the same year. There's nothing imprecise about it, it's just informal. Wouldn't it be weird if he had stated it down to the month or day? I think that's ridiculous. They have published timelines and there are thousands of people working on these films (including dozens to hundreds that check over the script and storyboards.) This was definitely intentional. Hard as it may be to accept, if you look at the facts, the conflict is purely between Iron Man 3 and Homecoming. Iron Man 3 in turn causes a ripple effect across several other films that simply do not exist without it. For example, the only reason Homecoming conflicts with The Avengers is that The Avengers seems to happen soon before Iron Man 3 which we are certain occurs in 2013. Marvel released this film knowing this conflict would exist and that Iron Man 3 would take the fall. If they could have avoided it, they would have, but it clashes with their plans to keep Peter in high school for his solo films. So they retconned knowing that Iron Man 3 would no longer fit quite right...it is the weakest link, goodbye. This is the timeline 2009: Iron Man 2010: The Avengers 2014: The Winter Soldier 2016: Age of Ultron 2018: Civil War, Homecoming If anyone can find me proof from the films that proves this timeline wrong (besides Iron Man 3 OR something like a blurry calendar in the background of a single shot) you win a No-Prize. In this timeline, for example...assuming Tony goes public in late 2009 and Civil War takes place in early 2018, Vision would be correct to say it has been eight years. A few months later, Homecoming and Avengers are also separated by eight years. In Civil War, General Ross remarks that the Avengers have been working without oversight for four years, placing the collapse of Shield in 2014. They probably did this so that Homecoming 2 would take place in 2019, the same year as it is released in theaters. There are props in the current film confirming that it is 2018. These props were custom-made so we can be certain that this was the filmmaker's absolute intention. That means we can also be certain that the "new" timeline places The Avengers between late 2009 and early 2011, about 8 years before Homecoming.
