Deus Ex: Human Revolution came out in 2011 as a prequel to Ion Storm's Deus Ex and Deus Ex: Invisible War. Human Revolution was made after Warren Spector left the company and Eidos closed down the Austin, Texas developer, leaving the franchise to Eidos Montreal. By the time of Human Revolution's release, Eidos was already purchased by the Japanese publisher, Square Enix. Deus Ex was set in 2052 and Invisible War was set in 2072. Human Revolution, being a prequel as mentioned earlier, rewound the clock to 2027 and introduced a new main character, Adam Jensen. It explored the rise of machine-human augmentations that formed much of the lore in the original titles.
Timeline and theme established, Square Enix has just announced Deus Ex: Mankind Divided, the sequel to the prequel with a great looking (albeit a little bloody) trailer. It is set in 2029, which is just two years after events of Human Revolution. It will be coming to the PC, as well as the two most-next-gen consoles. As expected, Adam Jensen returns as the main character. Now that Square Enix and its subsidiary, Eidos, spent so much to build him up as a brand, it makes sense that they would continue with the consumer recognition. Makes sense from a business perspective, although it probably means the franchise will meander less through time. I will leave that up to the reader to decide whether that's good or bad.
AMD Gaming has also tweeted out that Mankind Divided, or its PC version at the very least, will utilize both DirectX 12 and TressFX. I am curious whether TressFX has been updated to take advantage of the new API, given how important GPU compute is to the new graphics standards. No release date has been set.
