Well, there is another thing I'd like to bring about the first leak, considering the second, the one with the cover, might be true and mentioned Geras and Kronika.
If Kronika is the real deal, big bad and is possibly working with Raiden to erase multiple timelines (this makes much more sense about Dark Raiden than becoming a konqueror IMO, because this seems like "a greater good" he would try to achieve no matter what), and Geras is choosing warriors to go against them, considering the leak, what "multiple endings" did she appear in previous games?

Just a small BS I came up with a few years ago. In Shinnok's ending, the One Being eats the Elder Gods, and that reminded me a lot of what Chronos, the titan of time in Greek Mythology, does with his kids.
So I asked John Vogel if the One Being could be the Elder Gods' father, since he would not only eat them, but they had to kill the OB to become the rulers of the realms. There is one that is set to be the ruler of the underworld and seems like time started to be set after his "death".
He answered that that wasn't the intention and they were adversaries, as far as we know. Now that we can have a character named Kronika, goddess of time, I imagine what are the chances that this could have inspired him (who knows!) and what if she might be trying to reunite her father or something like this.
