Did Marvel And Disney Let One Slip Last Year?

Last year I left a post after watching Avengers: Infinity War that used the above photo.  The picture came from one of the trailers for the movie, and it was surprising that they showed the Incredible Hulk at the Battle of Wakanda when it was really Bruce Banner in the Hulkerbuster Iron Man suit.  I originally thought that they did this just to misdirect everyone from what actually happened in the movie, but a new fan theory has popped up saying that the above scene was actually from the upcoming Avengers: End Game movie.

Someone with the user name /u/BigMartin58 says that there are a few scenes that they believe are actually scenes from End Game, as opposed to Infinity War.  One of the things that they found in the original trailer was around the one minute mark in the trailer, he says that in the trailer it shows Tony Stark removing his sunglasses when the Q Ship arrived in New York after after meeting Dr. Strange.  In the movie, he armors up with his new nano technology suit and gets ready for a fight. In this person's theory, it is actually a scene from End Game and Tony isn't suiting up because he knows how it ended originally and may be taking a different route the second time around.

They also point out that in the Infinity War trailer Captain America seems to be lurking in the shadows longer than he actually did in the movie.  They claim that this is another situation where they are trying things different the second time around, since things didn't work so well for them the first time around.

Another thing that they point out is that in the teaser trailer, the Space Stone seems to be the first stone that Thanos goes after, while in Infinity War, the Power Stone was the first stone that Thanos obtained.  This is leading a lot of people to believe the earlier theory that time travel will play big part of End Game  is accurate.  They did show us a different Battle of Wakanda, after all.

Look, this could just all be cutting room floor footage, but I don't think so, and here's why.  The Hulk in the Battle of Wakanda seemed like a pretty finished product.  Also, the Russo brothers shot the two movies back to back, so why not mix up the footage? I mean, who would know until both movies were out, right?

We should all find out in just a couple of more months. Avengers: End Game will be released April 26, 2019.
