We've seen developers, voice actors, shareholders and more leak games before, but rarely stuntmen and stuntwomen. Lauren Mary Kim decided to be one of the first as her CV states that she's doing motion capture for "Shadows of Mordor 2". It would also seem that the highly acclaimed visual effects team Blur (know for their CG work in games such as Bioshock Infinite, Halo: The Master Chief Collection, Batman: Arkham Knight and more) is working on the game.
We already knew that Monolith has been working on an unannounced project for a couple of years now, and now it would seem a lot of peoples' hopes will come true. Bring on the Nemesis system 2.0!
