Interesting new details have emerged!
Recently TOEI released their financial report 2024 3 and it turns out that earnings showed a decrease in comparison to the previous year's earnings.
To the surprise of no one Saint Seiya The Beggining is to blame but not only this film it turns out that other productions are to blame for failing to reach expectations and the Sailor Moon Cosmos movies are mentioned.
The report is only in Japanese but when looking at previous financial reports something interesting appeared:
In a 2022 report Sailor Moon Cosmos is mentioned as an upcoming film for the Japanese market, but is has these words specifically: Movie Theater Version and this only concerns the Japanese market as these films are just presented as Japan IPs for now not Global IPs.
That basically means or confirms that the films will be released globally on streaming and probably Netflix will be once a gain in charge of this.
