This week/month/eon's fanthought was based upon an announcement Miyamoto had made. This was the announcement.
Miyamoto: Of course, Fire Emblem has been an important franchise for Nintendo for a very long time and Intelligent Systems has been working on it the entire time. We're always thinking about possibilities on how we can continue to use that franchise in the future and Mother 3 is something that Iwata and I have always talked about bringing to the users.
Well, I myself find this interesting because it seems like it was just thrown in there kind of randomly. Miyamoto was just like "Blah blah fire emblem blah MOTHER 3." It didn't seem to fit in there. However, I guess I sort of have future powers and can see that it didn't seem to bear fruit. Maybe they're still working on it in some underground laboratory though, and just want to keep it quiet! I don't know. For me, not much has changed, although I guess this is a bit better.
Now, on with your fanthoughts.
