Update: Pokémon Sunday has aired, revealing multiple aspects. First, there are new Sugimori artwork for the three starters. In addition, a short video of "gameplay" was shown (screenshot at left} with overworld sprites of Gold and Silver, with the selected starter, Chikorita, walking behind Gold.
Nintendo has confirmed a 2009 release for Pokémon HeartGold and SoulSilver, DS remakes of the principal Generation II Pokémon games, Gold and Silver, which were originally released for the Game Boy Color in 1999 in Japan. Speculated by fans to be in development since the release of Pokémon FireRed and LeafGreen, the remakes will take gamers back to the Johto region, found west of Kanto — this time as Generation IV games.
The games will most likely be able to link to Diamond, Pearl and Platinum as shown by game data.
HeartGold and SoulSilver will be released in Japan this fall, possibly on or near Nov. 21, the 10th anniversary of the original release of their namesakes. International releases will likely come in mid-2010
