Question: In what year did the publisher of Warlocked reveal 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 2: Picopict: "Picopict" was an anticipated release due to its presentation. Since its release, "Picopict" has received a very positive reception from publications such as IGN, GameSpy, and writer Stephen Totilo. It was nominated for best DS puzzle game of the year from IGN and won best DSiWare game of the year from Nintendo Life. It had critics, including Pocket Gamer and GameSpot, the latter finding it too difficult and imprecise. A fellow developer of downloadable video games, Gaijin Games, praised it for its gameplay and presentation. It received some attention in sales, appearing on the DSiWare's top 20 best-selling games chart for several weeks following its release, peaking at 10. It has been compared to "Tetris" by several people, though UGO's Paul Furfari bemoaned such a comparison, saying that its presentation set it apart.
Document 3: 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]
Document 4: Wizards of the Coast: Within a year, Wizards had sold millions of copies of the Pokémon game, and the company released a new set that included an instructional CD - ROM.

The two companies resolved their differences in December 2003 without going to court.

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.
