While Square Enix has not officially announced Deus Ex: Mankind Divided yet, images (concept art, mock ups or actual screens) have already been leaked.

Square Enix is currently Twitch streaming what looks to be building up to some sort of announcement.

Information from the just revealed GameInformer article.

Set in 2029, two years after the events of Human Revolution, Adam Jensen returns and joins forces with an Interpol-funded task force aiming to hunt down and capture augmented terrorists in a world that now hates and fears transhumans. Jensen has a new suite of augmentations that allow him to cleverly navigate stealth, combat, and social interactions, but how Jensen chooses to solve every problem is entirely up to you.

At the end of Human Revolution, the Illuminati caused every transhuman to go into a fight-or-flight response and attack anyone near them. In the next issue of Game Informer, you can find out how this event caused humanity to hate and fear those with augmentations. We spent two days in Eidos-Montreal's studio, talking with the team and learning about how they build a realistic future. We go in depth on some of Jensen's new augmentations that help improve the stealth and combat systems, such as the ability to remote hack electronic objects, fire off his nano blade from a distance, and surround himself with a nearly indestructible nanoshield. We also got some great examples on how the game will be as open ended as ever, allowing players to carve their own path through the world. You can only get these details in the latest issue of Game Informer.
