I'm not expecting a release of Mother 1 (Earthbound 0) Or Mother 3 (Earthbound 2) in the United States, ever. :(
RPGs don't appeal to casuals, and Nintendo stopped importing niche titles when people stopped buying them.
It's always good to repeatedly ask Nintendo and form grass-roots campaigns for these games, though.
If not for Mother 3, for Earthbound.
Thank goodness for English ROMs, though. :)
