Looks like they not only hired Chris Avellone but writers from CD project red as well. I have a feeling that this story and it's interactivity with your role playing decisions is going to break into new territory.
Also they are saying that the map is 4 times larger than Dying light's maps and it's expansion combined.
They made a pretty penny off of Dying Light and thanks to the Walking Dead the zombie theme still hasn't died completely from the mainstream. It looks like they have reinvested much of their profits to build the most ambitious game of the year.
