Question: In which year did Kirby's publisher unveil the start of development on what would become Twilight Princess?

full_context: Document 1: The Legend of Zelda: Twilight Princess: Aonuma had anticipated creating a Zelda game for what would later be called the Wii, but had assumed that he would need to complete Twilight Princess first. His team began work developing a pointing-based interface for the bow and arrow, and Aonuma found that aiming directly at the screen gave the game a new feel, just like the DS control scheme for Phantom Hourglass. Aonuma felt confident this was the only way to proceed, but worried about consumers who had been anticipating a GameCube release. Developing two versions would mean delaying the previously announced 2005 release, still disappointing the consumer. Satoru Iwata felt that having both versions would satisfy users in the end, even though they would have to wait for the finished product. Aonuma then started working on both versions in parallel.[o]

Document 5: The Legend of Zelda: Breath of the Wild: Similarly to the original Legend of Zelda (1986), players are given little instruction and can explore the open world freely. Tasks include collecting multipurpose items to aid in objectives or solving puzzles and side quests for rewards. Breath of the Wild's world is unstructured and designed to reward experimentation, and the story can be completed in a nonlinear fashion. Development of Breath of the Wild lasted five years. Wanting to reinvent the series, Nintendo introduced elements such as a detailed physics engine, high - definition visuals, and voice acting. Monolith Soft assisted in designing landscapes. The game was planned for release in 2015 as a Wii U exclusive, but was delayed twice due to problems with the physics engine.

Document 13: The Legend of Zelda: Twilight Princess: In 2003, Nintendo announced that a new The Legend of Zelda game was in the works for the GameCube by the same team that had created the cel-shaded The Wind Waker. At the following year's Game Developers Conference, director Eiji Aonuma unintentionally revealed that the game's sequel was in development under the working title The Wind Waker 2; it was set to use a similar graphical style to that of its predecessor. Nintendo of America told Aonuma that North American sales of The Wind Waker were sluggish because its cartoon appearance created the impression that the game was designed for a young audience. Concerned that the sequel would have the same problem, Aonuma expressed to producer Shigeru Miyamoto that he wanted to create a realistic Zelda game that would appeal to the North American market. Miyamoto, hesitant about solely changing the game's presentation, suggested the team's focus should instead be on coming up with gameplay innovations. He advised that Aonuma should start by doing what could not be done in Ocarina of Time, particularly horseback combat.[l]
