I would love for it to be Majora's Mask, but if it truly is just a remaster, N64-level graphics are going to look really dated. Something the level of GC/Wii will look much better remastered (ala, WWHD), and frankly, MM is better suited on the 3DS, with similar treatment to what OoT received.
If this really is true, I wouldn't be surprised if it was Eternal Darkness. When you consider that Nintendo re-registered the trademark last year, the fact that they need some theme diversity and the fact that not a lot of people got to play the original, it would be the most likely candidate to me.
