This year, between the 14th and the 16th of August, Disney held the D23 expo. Why is it so important? Because it was now when the fans had their first look at Captain America: Civil War, as well as the first concept art for Doctor Strange.
So yes, it was pretty exciting for those who were present at the panels "“ and, apparently, just for them, because nothing that was released at the D23 expo made it online. However, if you are looking for descriptions of everything that has happened, as well as for some news, check it out in here!
Civil War D23 footage description

First things first: D23 expo brought the first footage from Captain America: Civil War. Obviously, there wasn't too much to show. And there was no Spider-Man anywhere to be seen. But there were some awesome lines from the characters, as well, as some actions sequences.
Thus, the footage opens with Falcon, Black Widow, and Captain America taking on Crossbones. The villain says to Steve Rogers that the Winter Soldier regained his memory. William Hurt as General Ross talks with Captain America, telling him that the people don't know what to make of him: is he a hero, or a vigilante?
Scarlet Witch is also presented, in the same crowded setting in which the initial team fights Crossbones (and which is also believed to trigger the need for a Registration Act). Black Panther is also showed in full costume (which is said to resemble the concept art revealed by Kevin Feige last year), as well as Iron Man and War Machine, standing side by side.
There was no Vision in the D23 expo "“ however, there were to apparently hilarious scenes. In the first one, Black Widow fights Hawkeye "“ she asks if they are still friends, while he answers that it all depends on how hard he is hit.
The second one is with Ant-Man and Captain America. After waking up, Ant-Man meets the Captain and says, "thanks for thanking me"¦ thinking of me".
The Winter Soldier also appeared in the footage, saving a severely wounded Captain America from drowning (for more footage descriptions, from various sources, click this link!)
