''Legend of Zelda producer Eiji Aonuma has announced that meeting a 2015 release date for The Legend of Zelda for Wii U is no longer a "number one priority."
He clarified that during development, the team discovered "several new possibilities" for the game, which forced the team to reconsider their timeline and priorities.
"So, I must apologize to you all that were expecting the game by year's end, but we are no longer making a 2015 release our number one priority. Instead, our priority is to make it the most complete and ultimate Zelda game."
