A post to the Eidos Montreal blog has a post about what they are up to that includes plans for Deus Ex Universe, an "ongoing, expanding and connected game world built across a generation of core games" as well as a new Deus Ex game coming to Windows and consoles. They include a piece of concept art and this write-up from David Anfossi:

The concept behind Deus Ex: Universe is to create an ongoing, expanding and connected game world built across a generation of core games. It’s a commitment on our part to deliver meaningful content that expands the franchise on a regular basis and to deliver a deep conspiracy that will span several connected Deus Ex games, creating a more immersive and richer experience than ever before. Deus Ex: Universe will include PC and console games, but also additional Deus Ex games and experiences available in other media such as tablets, smartphones, books, graphic novels, etc... You might have seen the name pop up recently in the press – well this is what it’s all about. I’m pleased to confirm that we are already into production of the starting point for Deus Ex: Universe with a new game for PC and next-generation consoles. We’re very excited about it at the studio and I wanted to let you know that most of the team behind Deus Ex: Human Revolution is already working hard on this new game. It took us four years to learn how to create a unique Deus Ex experience with Human Revolution and it was important for me to keep this knowledge within the franchise.

I want to leave you with a piece of concept art from our next-gen Deus Ex game that shows trans-humanism segregation, which is a backdrop to our vision for the next Deus Ex. It represents a "ghetto-city' voluntarily built in order to separate the classes. The people in this segregated class have reshaped their environment, nostalgic for their ideal of Cyber Renaissance. This dark and dystopian vision sets the tone for things to come in Deus Ex. For now, I hope you are excited about the future of this game that we love so much. Deus Ex is coming to next-gen, it’s early so don’t expect to hear much more from us just yet, but I wanted you to know. I'm very excited as a developer and gamer!
