Canon Ending

It looks like Deus Ex: Mankind Divided has chosen the The Truth Is Out There ending of Deus Ex: Human Revolution as the canonical ending. You can see Adam Jensen in water surrounded by sinking rubble during the aftermath of the island plant's self destruction. Also, it is possible that the VTOL (vertical take-off and landing) aircraft that is seen above the water trying to retrieve Adam's unconscious body could be Malik's.

Persecution

The consequences of Adam’s choice at the end of Deux Ex: Human Revolution has taken quite an effect on the world. Persecution against augmented humans runs rampant.

Radicalism Begins

Attacks by an augmented terrorist group have begun as a result of the tense social climate between humans and augmented humans as well. Notice Eliza Cassan from Deus Ex: Human Revolution on the top right.

The Great Debate

The constant debate between humans and augmented humans from Deus Ex: Human Revolution continues further here. On the background building in this shot when Adam is pursuing a young terrorist, you can catch a glimpse of a poster that reads “Who Will Win? The Vote.” As an added note, if you are savvy with religious imagery, you'll notice that the human hand on the poster looks exactly like the hand of Adam in the famous Sistine Chapel painting, “The Creation of Adam."

Checkered Past

What gets Adam to defend the young soon-to-become a terrorist in the trailer is a vision of his failure to protect his ex-girlfriend, Megan Reed. Will she appearing? The post-credits scene during Deus Ex: Human Revolution revealed her to still be alive and working with the illuminati.

Hand Cannon

Adam will be able to make use of a non-lethal energy cannon that can send enemies launching. It appears to be a variation of the PEPS (Pulsed Energy Projection System) from Deus Ex: Human Revolution that is implanted directly into Adam's hand.

Augmented Angel

Following in the tradition of religious symbols in the Deus Ex series, we get a shot framing Adam with angelic wings.

Symbols from the Past

The hand and globe symbol from prior Deus Ex games return. Surrounding it are various companies, a few of which Deus Ex: Human Revolution players will recognize, such as Sarif Industries, Picus Group, and Versalife. For classic Deus Ex players out there, Versalife is the main antagonist organization from the first Deus Ex.

What's His Name?

From the computer screen on the right, the terrorist in the beginning of the trailer is named Ivan Berk. Will he play a vital role in the story of Deus Ex: Mankind Divided?

Stunning

Adam uses an augmentation that allows him to shoot taser darts from his knuckles. It looks to be a way to streamline Deus Ex: Human Revolution's stun gun.

Stick Around

As an added enhancement to his blades from the first game, Adam looks like he will be able to shoot his blades from his arms at will, effectively piercing enemies against walls.

Religious Practices

Ivan kissing the augmented hand of the terrorist leader simulates the Catholic tradition of kissing the Pope's ring.

The Hand of God

The debate between normal and augmented human runs even further this image of Adam’s hand reaching out to the hand of a deceased innocent caught in the terrorist bombing. This looks like the hand of God reaching downward to the hand of a human.

A Bolt of Gold

It appears that Adam can unleash a charge attack that he can use to collide into his enemies. The attack also shares some similarities from the Icarus Landing System from Deus Ex: Human Revolution.

Moral Quandaries

"This should be your fight as well, brother." Deus Ex: Mankind Divided looks to be creating another complex moral scenario for series fans to dive into. Will Adam be forced to make decisions that determine his allegiance?

Thick Skin

There seems to be an advanced version of the previous game’s Dermal Armor augmentation. This one seems to be a powerful shield that Adam might be able to trigger at will.

Fallen Angel

Once again, more angel wings. This time we get it from the lights of Malik's VTOL.
