Deus Ex: The Fall teased by Eidos Montreal

Deus Ex: The Fall teased by Eidos Montreal. Back in March 2013, Square Enix registered the domain 'Deus Ex: The Fall'.

Now today, Eidos Montreal's official Twitter account asks, "Are YOU ready for The Fall?"

Surely this means Deus Ex: The Fall will be revealed soon. Does that mean its Deus Ex 4, or its the film adaptation of Deus Ex franchise?

Update: A teaser revealed for The Fall stating a full reveal on Wednesday June 5th. Here's the trailer link on YouTube.
