Yes! (Kind of.) The Japanese broadcast for episode 75 of Attack on Titan ended with a short teaser confirming the title and the release window for episode 76, titled "Sentencing." The teaser doesn't reveal anything of note, but it shows quick snapshots of moments from all the previous seasons of the show, reminding us of the long journey to the final season. Is there an Attack on Titan Season 4 Part 2 trailer? That means that the next episode of Attack on Titan will premiere anywhere between the first week of January and the end of March. The first part of Season 4 was technically part of the 2020 Fall Season, but it premiered in December rather than October. However, Attack on Titan has been a bit different, premiering new seasons towards the tail end of the month.
When it comes to anime, new shows are released four times a year, with the Winter season starting in January, the Spring season starting in April, Summer starting in July, and then Fall season in October.
We currently don't have a specific release date for Season 4 Part 2 of Attack on Titan, but an announcement at the end of Season 4 Part 1 announced that the next episode was going to air in the “Winter 2022” anime season.
