I know it's already been floated by others, and dismissed by many, but there's something to the theory that the future of Powers of X is about Moira’s 9th life, with Apocalypse.
The data page in Powers of X 1 on surviving Mutants, the notation, while clearly Moira X’s files, is referenced as [ML_09........(APOC_build)].

In House of X 2, [Moira_L_TwoA] and [Moira_L_TwoB] are pages that tell the story of Moira’s second life. [Moira_L_Two] being the long form of the same notation, potentially abbreviated as [ML_02] would make sense.
We also have it made clear on the timeline of Nine, Moira and Apocalypse founded the X-Men, began working with Sinister, and her lifetime extends off the page, far past the “present day.”
Her Apocalypse-extended lifespan explains how Moira X knows about Rasputin IV, Nimrod’s Tower & Cardinal. The two unidentified Mutants on Asteroid K could be the Old Man/Apocalypse & Moira IX.
If they know of her powers, it explains Cardinals’s “next life” comment too.
Apocalypse and Moira IX are even fighting the same form of Nimrod and Tri-Sentinels we've seen in the Powers of X future in our glimpse at their war "without end."
