We saw many things in this 30 seconds!
1: Iron man's cool new weapon.
As you can see in the footage he has a portable repulser blaster with him. It also looks like it has a mini arc reactor in it.
2: Ant mans new suit!
Nothing much. It looks like a more slick back version of the original.
3: The most impressive. Black panther's claw marks on CaptainAmerica's shield!
It may be that black panther just scratched the paint. But it might also be that he piearced through the Vibranium! It is very possible because black panthers suit is a Vibranium weave.
