The Twilight Princess was scheduled to release in November 14, 2005.
"After much discussion, the Zelda development team has requested extra time to add new levels, more depth and even higher quality to Zelda: Twilight Princess. Consequently, we're announcing a new global launch in 2006, after the conclusion of this fiscal year (March 31). We'll provide a specific date at a later point in time. While this may come as a disappointment to many eager fans, it will absolutely enrich the game and make it a multi-million seller."
