http://www.escapistmagazine.com/news...anned-For-2010Development on a brand new entry in the Pokémon videogame series is already underway and it's planned for release on the Nintendo DS this year in Japan. No, we're not talking about Pokémon Ranger, Pokémon Mystery Dungeon, or even a revamp of Pokémon Pinball, the new title, or I likely should say titles, will be successors to Pokémon Diamond, Pearl, and Platinum.
http://www.andriasang.com/e/blog/201...ew_ds_pokemon/As relayed at Famitsu.com, the statement noted that the aim for new entries in the main series is to offer new Pokemon along with an adventure in a previously unseen land. The new title will also offer additional functionality and play elements and "will be an explosive hit that crosses the previous title."
A separate statement at the Pokemon official site noted that past DS Pokemon games have made use of the system's dual screen setup, touch screen functionality, and Wi-Fi support. According to this statement, the new title will add new forms of play and new Pokemon and will bring about a revolutionary rebirth to all areas of the series.
TL;DR: New Pokémon game coming 2010 (in Japan) probably 2011 for the rest of the world.
Sounds interesting can't wait to see what this "new form of play" will be and to see if the starter Pokemon are as crappy as generation IV.
