Nintendo are not the only ones that release fiscal year financial reports. Many other video gaming companies do a similar thing, including third-party companies. This also includes Falcom, who are the developers of the Ys games.
In fact, Falcom released an earnings report for the fiscal year that ended earlier this year, on September 30th. They confirmed that the next Ys game will be releasing by September 30th of next year. They also confirmed that, in Japan, they have plans to release 3 video games in the same fiscal year.
