IGN has put a preview for Guitar Hero III up on Xbox Live Marketplace in all its HD glory. The video gives us a first look at the new Les Paul wireless guitar, as well as some other cool features. One thing that impresses us was their use of face capture to have the lead singer properly lip-synced to the songs lyrics, as opposed to the previous iterations generic lip service. The video also touches on some of the visual changes, in the HUD as well as the art direction. A solid watch, if you're a fan of the series.
