Now, as much as I wish this to be true (so that we Lumineth Realm-chads can keep on winning 😎) I take issue with the fact that it fails to mention any other new Destruction armies in what’s meant to be the destruction edition. Death got like what, 3 in 2e? So you’d expect there to be more.
Plus, I’m not gonna put it here but I saw the leaks on /tg/ itself and they get more and more unreasonable, claiming to know the exact way 3e is gonna end - which is just plain unrealistic, GW might plan model release far in advance, but not the story. So therefore, this is probably a fake.
