Honestly, it seems pretty clear to me that he's not referring to Zelda U. The only mention of the Wii U is speculation on the part of the article's author. And the fact that he says 'future' indicates to me that it's a game that hasn't been started in earnest yet (which Zelda U most certainly has), most likely for the 3DS. I don't think there's any need to panic and get our pitchforks out just yet.
