Nintendo of Europe has announced that it will be releasing Pokemon Stadium 2 (called Pocket Monsters Stadium Gold and Silver in Japan) in Europe later this year.
The game features the same Transfer Paz snazzery as the original, with all Pokemon for Red/Blue/Yellow/Green and Gold/Silver included.
The cartridge will be a half gold, half silver affair as pictured, in the same vein as the Zelda games and the new Pokemon duo.
