Will the next steps involved in the Zodiac weapon quests, following Animus, be focused on individual play or rely on parties? Or will it be a combination of both?

The relic had a few individual elements but many involved trials that required parties to complete.
The atma was individual and required grinding fates to obtain the crystals.
The animus, for the most part, is individual, being able to do leves, slay specific monsters, with the exception of some of the fates being difficult to solo, and having to have a party for the dungeon requirements.
