Actually, you might not be that far. I found this interview recently (which I don't think I've ever seen before... maybe we should get someone to really translate it...), and through the magic of google translation (which is sooo bad. Japanese is so hard to translate) I think she said something along the lines of her readers being very passionate about the series and urging her to continue. But then again, I could be totally wrong because the Google translation makes very basic sense and Babelfish won't work for it...
