Several Pokemon Games Announced
Four Pokes Planned
According to Japanese publication, Comic Korokoro, Nintendo has plans to release three Pokemon games in the upcoming future. The games will run the gamut of genres, including a puzzle game, Pokemon Torouze. Pokemon Torouze has the player match specific columns of Pokemon, similarly to games like Tetris and Puyo Pop.
The other two titles are Pokemon: Fushigi no Dungeon Blue (a Red version is planned for the Game Boy Advance), of which little information is known and Pokemon Ranger, an action-RPG that will tie-in with the upcoming movie and anime series.
Important to note that neither of these games are (nor taking the place) of Pokemon Diamond and Pearl; both titles are expected to release some time next year and follow in the vein of prior Pokemon RPG titles on Game Boy and Game Boy Advance.
