Unfortunately for EarthBound fans, there won't be another game in the series.
According to these Japanese archives, a fan recently asked creator Shigesato Itoi to consider making Mother 4 (the Japanese title of EarthBound). Itoi's response was a very simple, "Impossible." So, alas, it looks like we won't be seeing another instalment in this charming yet tragic RPG series.
Why not? Who knows - but the fact that Mother 3 spent a legendary amount of time in development hell, with work beginning in 1994 for the SNES and being released over a decade later on the Game Boy Advance may have something to do with it. Maybe Itoi-san doesn't want to spend that long developing a game again. Or perhaps he's just decided that it's time to move on with his creative life and do something else.
It's not a huge surprise, though, as this isn't the first time he's declared a lack of interest in making Mother 4. When he revealed last December that he was working on something related to the franchise he stressed, “It’s not 4! We’re trying to get Mother working again right now. I still can’t mention any details, but I have to make clear that this isn’t ‘4’!”
In hindsight, he was probably talking about how EarthBound will be available on Virtual Consoles in North America and Europe later this year. No exact release date has been set but it's definitely worth getting excited about - especially since it'll be the first time the game has ever appeared in the PAL regions, which gives us hope that even more NTSC-only games will make their way over here in due time.
