>>108679849I unraveled the key about how they are doing it with this season. 26 episodes, 12 months in the year. 2 episodes for each month, with 2 months with 3 episodes. They haven't followed regularly this rule, however:
+ December 2018: 2 episodes.
+ January 2019: No episodes.
+ February 2019: 3 episodes.
+ March 2019: 2 episodes.
+ April 2019: 1 episode.
+ May 2019: 4 episodes.
+ June 2019: 1 episode.
+ July 2019: (In progress) 2 episodes.
Now, let's make balance:
+ Move December's episodes to January.
+ One May's episode to April.
+ One May's episode to June.
This way, we have 6 months with 2 episodes, and one with 3 episode (February). Now, unless they want to turn July in another month with 3 episodes, I think we won't have more episodes until next month.
It is said we will have a preview for "Ikari Gozen" at SDCC 2019, but I don't think that will count.
