This is not a new Mother (aka Earthbound) game announcement—well, not yet at least. However, it is an announcement that the scripts from all the Mother games will be released later this year in Japan. There will also be other Mother-related announcements before then. Hopefully, that means some Switch ports!
I like the idea of releasing game scripts. I double-check them sometimes if I’m writing about a game or returning to a plot point. Rewatching Let’s Plays or keeping a store of screenshots is vastly less efficient than flipping through a book, let alone using Ctrl+F on a PDF scan or text file.
