No worries. Lindsey over at the Yomuka! blog has you covered. She recently translated into English the above-mentioned interview--in which Shigesato Itoi not only chatted (briefly) about a Mr. Saturn spin-off (an action-puzzle game, to be more specific), but also discussed his original intent to make Mother 3 two-dimensional (back when it was still a Nintendo 64 game), his role in naming the Nintendo 64 and more.
Is it strange that I drooled over this screenshot as a teen?
Despite its age, the translated interview--which can be found here--is well worth a read if you're any kind of Mother/EarthBound fan (and, really, what self-respecting gamer isn't?).
