The Fandom Post is reporting that the Anime Strike channel has been removed from its Amazon Video site. According to the report, anime such as Made in Abyss, Welcome to the Ballroom, and Re:Creators have been moved into the standard tier.
The report noted that some of the first Winter 2018 season simulcast announcements have been conspicuously absent of mentioning any Anime Strike branding or distribution. Apparently, the shows that are part of the Noitamina and Animeism block venture are available for viewing without the additional Anime Strike charge in the United States, it is not known yet whether this will be the case for international users or not.
