I'm going to do the typical answer and tick Majora's Mask because it probably will be remade and could even be next year. Wind waker only took 6 months because they had a second team making HD Textures while a small team made new features like the Tingle Bottle. Basically all they will need to do and done.
I still think Twilight Princess or Skyward Sword need some kind of HD Collection. No point in giving it new visuals, just do like loads of PS3 games did and just bring it to HD and done.
