Ubisoft has release a video and a press release on what to expect from their E3 2016 conference, and it looks like things will be jam-packed for the developer/publisher.
The press release details that "Watch Dogs 2, For Honor, and Tom Clancy’s Ghost Recon Wildlands" will be making an appearance during their conference. However, Ubisoft did not detail what would be showed for each game. Without those details we can't be sure whether we will be seeing gameplay, cinematic trailers or simply seeing concept art.
In addition to those games, Ubisoft teased that there would be "some surprises" during their E3 event.
For Honor, Wildlands, South Park The Fractured But Whole, and Eagle Flight will all be available at the Ubisoft booth for fans to "further explore the lineup."
You'll be able to catch Ubisoft's E3 2016 pres conference on June 13th, at 1:00 PM PT.
