The Game Boy Micro is about the size of an iPod Mini. It measures 4" x 2" x 0.7" and weighs just 2.8 ounces. A removable face plate, similar to those on Nokia phones, will let users customize the device. The Micro will play the same games as the current Game Boy Advance SP, but has a brighter screen than its forebears. The Micro will be released this fall, Nintendo officials said, but did not announce a price.
