Yeah, I really have no idea how they'd measure "demand". There have been a lot of other April Fool's jokes labeled as such on joystiq today though, and I think this article might be legit because it's not labeled as such. Anyway, I can't prove that the interview actually exists until someone with the issue of Nintendo Power confirms it. The only way I could possibly see people demonstrating their demand is either signing a petition (and we all know how much weight Square Enix gives to these) or if SE themselves hosted a poll on their website. At any rate, I figured I might as well share the information since it's better than nothing.
