Feels like the way the Syndicate guy enumerated the events is how they would go in order tho...

Like he mentioned Hyril'ar which is basically where Orion and Caly end up by the end of this update and where the first quarter of next update likely takes place. It's then followed by "the genocide," so that event could follow right after, then the loss of Orion's loved ones and the end of everything, which sound like bad endings (tho Cari gave warning on Discord that 0.9 or 0.10's cliffhanger is going to be just as brutal as 0.7's, so the "loss of loved ones" thing could happen then or something close to it happens which Orion will likely try to prevent).
So I don't really buy that the genocide is referring to the Xenomorph culling. Could be wrong, but eh, we'll see I guess.
