What will the upcoming arc/s cover?
I think we may see more Yor / Yor x Loid and Garden centric content. Possibly Yor's backstory from her perspective and Yor's assassin reveal to Loid. Based on chapter 120 the Desmond plan seems to be deprioritized over understanding Yor(Pausing the mission to get an understanding of his wife is definetly for the mission).
Many have theorized that Yor and Loid's identity would be revealed at the same time when facing against each other it is plausible but I think revealing you're an spy of an "enemy" nation carries a bigger weight than revealing you're a member of SSS or an Assassin of that nation.
It would make a good near ending arc for Yor to realize the whole family was a sham the Loid Forger she loved didn't exist it was just another Identity for Twilight she would end up leaving due to conflicting feelings, and Loid would only realize his feelings for Yor when she is gone and would have to choose between his mission or Family.
We could also see betrayal of their respective agencies like Loid not informing WISE about Yor being an Assassin from the Garden and Yor not informing the Garden about Loid being a spy because doing so would probably result in being given a task to eliminate each other.
