Question: What's the date when the publisher of Pokémon Channel announce the new systems?

full_context: Document 1: Pokémon Yellow: Like Pokémon Red and Blue, Yellow takes place in the region of Kanto, which features habitats for 151 Pokémon species. The objectives remain the same as well, though some differences exist along the way. For example, in the beginning, the player is not given an option of choosing one of three starter Pokémon. Instead, a wild Pikachu that Professor Oak catches becomes the player's starter Pokémon, while the rival character takes an Eevee. The plot is loosely based on the Indigo League saga of the anime, and features characters that were not featured in the game or have been enhanced to resemble their designs used in the anime, including Jessie, James, Meowth, Nurse Joy and Officer Jenny. Similar to the anime, Pikachu refuses to evolve. Players are also given the opportunity to obtain the original three starters. As players quest on, they gradually progress catching Pokémon for the Pokédex which you use to defeat the eight Gym Leaders and eventually the Elite Four, all the while battling Team Rocket, a gang devoted to using Pokémon in order to make themselves more powerful. By the time of the encounter with the Elite Four the player has had the opportunity to capture 149 types of Pokémon; in the after game (after the Elite Four is defeated) a player may enter Cerulean Cave, where Mewtwo, the final Pokémon in regular gameplay, can be found, battled and captured. The last Pokémon in the Pokédex, Mew, can not be captured during ordinary gameplay, though exploiting bugs in the game makes this possible.

It is one of several "Pokémon" games to be based on the "Pokémon" anime, and features Ash Ketchum and other characters featured from the anime. The game was released on the Virtual Console on May 5, 2008, in the North America region, and on May 30, 2008, in the European region.
Document 3: Nintendo Entertainment System: At June 1985's Consumer Electronics Show (CES), Nintendo unveiled the American version of its Famicom. This is the system which would eventually be officially deployed as the Nintendo Entertainment System, or the colloquial "NES". Nintendo seeded these first systems to limited American test markets starting in New York City on October 18, 1985, following up with a full-fledged North American release of the console in February of the following year. Nintendo released 17 launch titles: 10-Yard Fight, Baseball, Clu Clu Land, Duck Hunt, Excitebike, Golf, Gyromite, Hogan’s Alley, Ice Climber, Kung Fu, Pinball, Soccer, Stack-Up, Tennis, Wild Gunman, Wrecking Crew, and Super Mario Bros.h[›] Some varieties of these launch games contained Famicom chips with an adapter inside the cartridge so they would play on North American consoles, which is why the title screen of Gyromite has the Famicom title "Robot Gyro" and the title screen of Stack-Up has the Famicom title "Robot Block".

Document 5: Nintendo Entertainment System: As the 1990s dawned, gamers predicted that competition from technologically superior systems such as the 16-bit Sega Mega Drive/Genesis would mean the immediate end of the NES’s dominance. Instead, during the first year of Nintendo's successor console the Super Famicom (named Super Nintendo Entertainment System outside Japan), the Famicom remained the second highest-selling video game console in Japan, outselling the newer and more powerful NEC PC Engine and Sega Mega Drive by a wide margin. The console remained popular in Japan and North America until late 1993, when the demand for new NES software abruptly plummeted. The final Famicom game released in Japan is Takahashi Meijin no Bōken Jima IV (Adventure Island IV), while in North America, Wario's Woods is the final licensed game. In the wake of ever decreasing sales and the lack of new software titles, Nintendo of America officially discontinued the NES by 1995. However, Nintendo kept producing new Famicom units in Japan until September 25, 2003, and continued to repair Famicom consoles until October 31, 2007, attributing the discontinuation of support to insufficient supplies of parts.
Document 6: Pokémon Go: Pokémon Go is a free - to - play, location - based augmented reality game developed by Niantic for iOS and Android devices. The game was the result of a collaboration between Niantic and Nintendo, by way of The Pokémon Company, and was initially released in selected countries in July 2016. The game utilizes the player's mobile device's GPS ability to locate, capture, battle, and train virtual creatures, called Pokémon, which appear on the screen as if they were at the same real - world location as the player. The game features a freemium business model and supports in - app purchases for additional in - game items.
Document 7: Nintendo Entertainment System: Video output connections varied from one model of the console to the next. The original HVC-001 model of the Family Computer featured only radio frequency (RF) modulator output. When the console was released in North America and Europe, support for composite video through RCA connectors was added in addition to the RF modulator. The HVC-101 model of the Famicom dropped the RF modulator entirely and adopted composite video output via a proprietary 12-pin "multi-out" connector first introduced for the Super Famicom/Super Nintendo Entertainment System. Conversely, the North American re-released NES-101 model most closely resembled the original HVC-001 model Famicom, in that it featured RF modulator output only. Finally, the PlayChoice-10 utilized an inverted RGB video output.
Document 8: Nintendo Entertainment System: In the UK, Italy and Australia which share the PAL A region, two versions of the NES were released; the "Mattel Version" and "NES Version". When the NES was first released in those countries, it was distributed by Mattel and Nintendo decided to use a lockout chip specific to those countries, different from the chip used in other European countries. When Nintendo took over European distribution in 1990, they produced consoles that were then labelled "NES Version"; therefore, the only differences between the two are the text on the front flap and texture on the top/bottom of the casing.
Document 9: Nintendo Entertainment System: For its complete North American release, the Nintendo Entertainment System was progressively released over the ensuing years in four different bundles: the Deluxe Set, the Control Deck, the Action Set and the Power Set.

In 1989, the Power Set included the console, two game controllers, a NES Zapper, a Power Pad, and a triple Game Pak containing Super Mario Bros, Duck Hunt, and World Class Track Meet. In 1990, a Sports Set bundle was released, including the console, an NES Satellite infrared wireless multitap adapter, four game controllers, and a dual Game Pak containing Super Spike V'Ball and Nintendo World Cup. Two more bundle packages were later released using the original model NES console. The Challenge Set of 1992 included the console, two controllers, and a Super Mario Bros. 3 Game Pak for a retail price of US$89.99. The Basic Set, first released in 1987, was repackaged for a retail US$89.99. It included only the console and two controllers, and no longer was bundled with a cartridge. Instead, it contained a book called the Official Nintendo Player's Guide, which contained detailed information for every NES game made up to that point.

It also introduced the basic game concepts of capturing, training, battling, and trading Pokémon with both computer and human players. These versions of the games take place within the fictional Kanto region, inspired by the real world Kantō region of Japan, though the name`` Kanto'' was not used until the second generation.
