POSSIBLE SPOILERS
New Avengers 4 set images confirm something we’ve expected with the other set images: time travel. Tony, Cap, Hulk, and Ant-Man are shown in the images and Captain America is wearing his costume from the first Avengers movie. You will also notice the actors are wearing orange mo-cap dots, as well as some device on their hands that is probably Stark tech that has to do with time travel. I’m intrigued.
