Mother 3 looks to making its way to Nintendo Switch Online in Japan. It was not announced during the Nintendo Direct February 2024 edition.
Not true. It would require Nintendo to make an English translation. The one we have isn't an official translation.
Not necessarily; there are a few SNES games in the Switch Online library that weren't localised and hence remain untranslated from Japanese, namely Super Puyo Puyo 2, Panel de Pon, Mario's Super Picross, and Kirby's Star Stacker. Though all of those games are puzzle games, which don't necessarily need language to be enjoyed, whereas an RPG like Mother 3 would likely be much less enjoyable without understanding the dialogue, battle UI and so on.
