Confirmed at Nintendo's surprise direct that just happened a few minutes ago. Personally I'm not that big on the 3D Zelda games but it'll be fun to replay this again. Coming Spring 2015.
Majora's Mask is my favorite 3D LoZ game, so I'm pretty happy it's getting a port/remake. I think everyone kinda knew it would get one eventually since OOT got the same treatment first.
Dissapointing. Majoras big point were it's graphics (for it's time). While a remake is cool, a half-way remake (or more like an improved port) for just a generation ahead of graphics isn't that dandling. I would preferred it for the WiiU, or for the next generation, but whatever. Hipsters will be happy with anything anyway, they just want it to become more popular (not a bad thing anyway).
