While waiting for Diamond/Pearl Nintendo decided to surprise us once more revealing the first screenshot of the new Pokémon game for Wii. They also stated that it will somehow utilize the WiiConnect24 (the online service that Nintendo has planned for the Wii) and that it will be compatible with Diamond/Pearl which will have a voice chat feature.
Fild.de now has a gameplay video.
