A European trademark for 'Deus Ex: Mankind Divided' has been spotted and was filed by Square Enix back on March 14th. It covers all spectrums with 'computer software' and 'video games' being repeatedly mentioned.
Eidos Montreal are putting all their Deus Ex efforts under the single umbrella of 'Deus Ex: Universe', which is to encompass all future and connected experiences. A casting call was found last week.
Voice work for an Illuminati Shadow Agent who would "infiltrate the Augmented Rights Coalition" was spotted, but no Deus Ex name was attached. A new title is in the works.
Given that there's an 'Augmented Rights Coalition' and the trademark is for 'Mankind Divided' it's likely we have the name of the upcoming new PC, Xbox One and PS4 Deus Ex title from Eidos.
