I doubt the 'leak' for a few reasons, namely:
- No returning Cyborg, despite him being in the Justice League movie.
- Captain Cold instead of Captain Boomerang for a Flash villain. If they wanted an 'ice' villain and already have Mr. Freeze going with Killer Frost seems like a better pick, especially considering that she was in Injustice 1.
- No returning Ares, despite the Wonder Woman movie (though Netherrealm may not have known the Wonder Woman movie until it was too late)
- Too many clones. Zoom, Power Girl, John Stewart. Power Girl would probably be a Supergirl set of armour, I imagine.
I'm going with fake.
