Effective trailer despite not showing much. It looks like the world is rocked and in mourning. Not a lot of heroes left. But the ones who are left, after grappling with grief, are preparing to Do Something.

(Maybe it's more than just a "futile and stupid gesture" like Animal House, although at this point anything is good.) it is feeling like some amount of time has passed... not sure how much, but it's not just like the Snap happened yesterday. I'm not sure how long it takes Tony and Nebula to get back either.

Here's the original trailer from some weeks back.

Note that there are notable gaps between characters in a few shots (compared to the spacing of all the other characters in the frame) -- the guess is that they CGI'ed Captain Marvel out at least until her movie releases in a month.
