Already released in Japan to monster sales, the three million–selling Pokémon HeartGold/SoulSilver has been dated for the US market.
The games are remakes of Game Boy titles Pokémon Gold and Silver, and their 2009 release in Japan correspond to the 10th anniversary of the titles. The games are bundled with a pedometer called the "Pokéwalker", which can increase experience and in-game currency. These peripherals can also be used to trade items.
HeartGold/SoulSilver will be out in the US on March 14.
