Nintendo has announced it will be holding a Nintendo Direct broadcast tomorrow, January 14, at 6 a.m. PT, 9 a.m. ET.
The presentation will center around 3DS and Wii U content coming this spring. Seeing as how the New 3DS still hasn't been announced for North America, I suspect we'll finally get a proper announcement along with a release date. We'll probably get a release date for Majora's Mask 3D as well, which I suspect will be launching the same day.
On the Wii U front, we know Kirby and the Rainbow Curse as well as Mario Maker are set for release relatively soon, so perhaps we'll get more information on those titles as well.
