The next major iteration of Guitar Hero will be the first Wii rhythm title to offer DLC in the form of new tracks that can be played from the SD card.
In a recent interview with Game Daily Karthik Bala, CEO of Guitar Hero World Tour developer Vicarious Visions, revealed that the Wii version of the game will feature downloadable content. Players will be able to purchase and download additional song tracks for the rhythm game in order to continually expand their selection beyond the songs that ship on the disc. No Wii game prior has featured downloadable content to this extent.
Though this news in and of itself is fantastic, Bala revealed yet another enticing detail: players will be able to play tracks directly from an SD Card. Tracks saved directly to the SD card are referred to in-game as the Rock Archive and players can group them into a custom set and play them in any of the game's venues.
Karthik Bala also revealed to Game Daily that the downloaded music will be stored "in a custom format for Wii so it's as compact as possible, but still sounds great."
Guitar Hero World Tour will be available for Wii on October 21.
