The Legend of Zelda : Skyward Sword has sold more than The Legend of Zelda : Majora's Mask and The legend of Zelda : Spirit Tracks which is quite good for "the SECOND Zelda game on a platform".
The Legend of Zelda : The Wind Waker HD will probably move an acceptable amount of units for a remake of a ten years old game. It might move more hardware than God Of War Collection or Jak and Daxter Collection...
