Ha ha ha. The retro look is for a Guitar Hero “Rockumentary” that will be part of a Guitar Hero interactive display that will be featured at American Idols Live concerts across the country. From the press release:
The 10 …Idol tour finalists will be part of a halftime Guitar Hero World Tour rockumentary, created by advertising agency DDB, that blends the camaraderie of hanging out in the studio with the franchise latest transformation of music gaming – a slick newly redesigned guitar, a genuine electronic drum kit and a microphone. In each city, expert shredders will also face-off on center stage, and Guitar Hero: Aerosmith and Guitar Hero: On Tour will be available for everyone to play in a booth throughout the tour.
