Nintendo has announced a new device that will come along with Pokémon HeartGold and SoulSilver. Named the “PokéWalker,” the device is reminiscent of the Pokémon Pikachu virtual pets.

Like the older devices, the PokéWalker has a built in pedometer that counts your steps. Steps will transfer into experience points and happiness for a Pokémon of your choice, which you will be able to upload from your HG/SS cartridge. Mini games are said to be included as well. Also like its predecessors, there will be a currency called “Watts” which you will be able to spend on items and other mystery gifts which will be transferable back to the DS cartridge.

Rather than being shaped like a mini Game Boy, it will look like a PokéBall. It has a three button design and a grayscale screen, approximately .7 inches tall by 1 inch wide. The diameter of the device is about 1.8 inches and the thickness is approximately .5 inches.

Stay tuned for more details as they become available.
