After the devastating ending in Avengers: Infinity War, the newly leaked promo art could give fans some inside hints to the future release. If you haven’t seen Infinity War, please look away now.
The most noticeable difference is in Hulk’s attire.
It appears that the remaining cast also has new apparel or using updated looks featured in Infinity Wars as well.
The second promo photo leaked is of Thanos. He is shown with the sword which has been featured in previous movie concept art.
With all of these images, the photos appear pretty legit, or fantastic fan art.
