I have added Type Affinity to every Info page on the Pokédex which makes it easier to see to what types a Pokémon is resistant to or has a weakness against.
In other news, Junichi Masuda (the director of Pokémon Diamond and Pearl) said in his “Director’s Column” (translate) that he would like the games to be Wi-Fi enabled and unrestricted by borders and languages. He says that working with two screens, a touch screen and wireless communications is difficult but the development goes on smoothly. Bulbanews also has a story on it.
