Nintendo's Revolution will be significantly smaller than its rivals', about the size of several stacked DVD cases, and will come in several as-yet-undetermined colors.
At 4 inches wide and 2 inches tall, with a 2-inch screen, the Game Boy Micro will weigh about 2.8 ounces and play the same games as the Game Boy Advance SP.
The Revolution release is critical for Nintendo, which has fared the most poorly of the three major console companies over the past years.
The Revolution will play DVDs, have built-in Wi-Fi and an SD memory card slot, and 512MB of flash memory, the company said.
