In addition to the release date announcement for Dues Ex: Human Revolution Director's Cut, studio head David Anfossi also revealed they are working on a new concept called Deus Ex: Universe. They are already in production on a new game as the starting point.
The idea for Dues Ex: Universe is to create a continuous, expanding and connected game world that encompasses the generation of core games, as they want to continue to develop the franchise with more meaningful content. The project will not only include PC and console versions, but also additional games for devices such as tablets and smartphones as well as books and graphic novels.
The new game that is already in production will be targeted for the PC and the next-generation consoles. Here is a concept art image they have released.
