How many weeks do we need to keep doing the Nier weekly quest?

I suspect, as well as with the Warring Triad/Role quest epilogue, that they are planning to lock a piece of Endwalker content behind Dark Apocalypse just as Bozja was locked behind the Ivalice raids.

Seems unlikely to me with the Nier raids being a a seemingly over and done crossover on the First only affecting one dwarf village.

This is probably just a reference to how you had to beat Nier over and over to get all the endings or something, there was a lot of grindy fetch quest side quests and gameplay repetition in the Nier games.
