Nintendo's annual trade show in Tokyo, watched by video game fanboys and girls alike, where many new products are unveiled and announced for sale in Japan. Some, like the 64DD and Game Boy Light, never make it to the U.S.; others, such as the Game Boy Advance, become quick successes on both sides of the Pacific.
Most video game magazines and large web sites send at least one person to Spaceworld every year to get the inside scoop. When the captures come back from Japan, the speculations on release dates immediately begin.
