Halo trilogy theme on XBL

Halo fan geekdom has jumped another spot again today, as Microsoft has announced that a Halo trilogy theme for the Xbox 360 is now available on Xbox Live. The theme, which adds images to the background of Xbox 360 dashboards, costs 150 Marketplace points ($1.87) or is free for those who preordered the Halo 3 Xbox 360 faceplate. Xbox Live's Major Nelson reports that the theme features "never-before-seen scenes" from the Halo trilogy, including "all three iterations of the Master Chief's iconic Spartan armor."
