You know the supposed Guitar Hero: World Tour keyboard that never materialized? If you were really looking forward to that, get ready to have your hopes dashed on another mystery instrument that will probably also never come to be. According to Harmonix, that extra port on the back of the updated drum kit -- which previously was said to be for a second kicker -- is actually for something that's totally not a second kicker. What exactly will fill that port, though, the company isn't saying. Speculation is rife about another nebulous keyboard peripheral, but if you ask us our money's on a high hat, or maybe that other fundamental aspect of the drumming experience yet to be captured in the silly plastic instrument game genre: the triangle.
