The Gold Nunchuk was first introduced as a North American Club Nintendo reward back in August, but quickly sold out. Nintendo likes to mention in the product description that this reward goes great with the limited edition Zelda Gold Wii Remote that was bundled with some copies of The Legend of Zelda: Skyward Sword.
