Players will unlock a new difficulty level after completing A Link Between Worlds. That comes directly from Eiji Aonuma, producer of the series.

Gameswelt has obtained information from Aonuma about A Link Between Worlds’ development as well. Over 90 staffers worked on the game, and first ideas for the game were collected after Spirit Tracks was completed.
