It's About How Much We Have Left: New Avengers Endgame Teaser!

I'm on Twitter and I notice "AvengersEndgametickets is trending. First of all, I should've known getting tickets would be a battle. Secondly, I'm seeing all these new screenshots from the movie. So, yup. We got a new teaser! Confirmation that Tony made it back to Earth! I thought Tony was going to die coming into Earth. I thought that scene with them in the white suits was a tease like that one from Infinity War with Hulk and everyone running through the forest.
