Wii U Daily reported on Wednesday that The Legend of Zelda for Wii U will be released in 2014 and will be Nintendo's most expensive game ever. The art style will be in the vein of 2011's The Legend of Zelda: Skyward Sword, though with a new engine.

"It's a 4-year development cycle with a new console, new technology, new engine etc. It'll end up being the most expensive game they've made to date. It's a huge investment for them [Nintendo] in money and manpower," the source claimed and revealed "hundreds" of people are working on the title.

"This is the biggest project they've [Nintendo] ever done, no way is it gonna be ready for Q3 2013," opined the source. The 2014 release date came after originally targeting the game for fall 2013 to combat Microsoft and Sony's probable next-generation consoles.

The information comes from a source that saw the game in action and previously leaked information on the social network Miiverse and achievements that would come to Wii U. The source seemingly is a Nintendo employee, though his role in the company was not specified.

Skyward Sword was described as a "sweet spot," though the report does not specify whether in terms of graphical and/or formulaic approach. Edge Magazine labelled it a "triumph" for Wii as it displayed the console's and Wii MotionPlus' full capability. Eiji Aonuma will continue heading the game's development, as he did Skyward Sword. While the art style of Skyward Sword continues, the high definition capability of Wii U may fully realize its vision.

Additionally, the development team is the biggest ever, rivaling Grand Theft Auto developer Rockstar in size.

The game allegedly features the same number of dungeons as previous Zelda titles, though they are considerably larger. An early forest dungeon is reportedly the size of Ocarina of Time's overworld, and some dungeons will be multi-part, requiring "hours" to complete. In Skyward Sword, Nintendo aimed to create a seamless world after criticism over previous games' fixed structure.

Wii U's release date remains to be announced.
