I still think that the real 3D Mario will be announced and released this year.

I think that a real 3D Mario game will be announced this year, but released only 2015. Majora's Mask remake can be announced too, but I'm not sure for which plataform nor if it is happening this year, since it is close to Zelda 30th birthday, I think Nintendo will announce some kind of HD Collection for Wii U. Not sure about a 2D Metroid game, but both 3DS and Wii U can do nice things for a 3D Metroid game.
