When are they going to reveal Sanby is the lynchpin to the game's story and justify her being the face of the game?

Paimon started getting heavy implications of being some greater thing than a sidekick from the jump and not it's 5.X and it's heavily implied she's on the level of an archangel to genshin's gnostic demiurge esque god or potentially that god.
HSR is finally going to show what March is and reveal some backstory in a patch or two.

Will we get Anby crumbs at the end of 2.X or 3.X?
