But it's also a good point to re-introduce the series, if they do go end up going through with Mother 3 being translated. I mean, really, Mother 3 has very little to do with the other two games in the series, if one looks at it from an outside point of view. There's Porky and Dr. Andonuts and some random other tiny references, but you don't really need to play EB to *get* it, unlike a lot of sequels.
Plus I always kinda felt that they didn't necessarily need to call it 'EarthBound 2' in the US. Maybe a title similar to EarthBound? ..Islandstuck? /shot
From what I've read, Nintendo just kind of wants to forget that EB existed, and with Mother 3 they could always kind of do a 'reset', I guess? I dunno. :V (I'm terrible at debating this kind of stuff, okay.)
