Brace yourself -- the moment you've been waiting all year for has finally arrived. Yes, rock star wannabes, the Guitar Hero Air Guitar Rocker is finally in major retailers. The Jada Toys' device, which was showcased at CES, consists of a miniature guitar amplifier, a sensor-laden belt buckle, an assortment of pics and an Air Cartridge, which packs "ten signature guitar riffs" ranging in skill from one to five. Once you rock the wind out of the $29.99 base unit, you can look forward to "encore packs" -- which will include themed belt buckles and new Air Cartridges -- arriving later this summer for $14.99 each. Oddly enough, we think a "gnarly" is order here.
