Guitar Hero World Tour can save DLC to an SD card

Vicarious Visions' Karthik Bala has once again
confirmed paid downloadable content in the Wii version of
Guitar Hero World Tour, though
current Wii guitar
games have left us doubtful of
any feature.
Furthermore, you'll be able to save your songs to a "Rock Archive" on an SD card, and even play songs from the card without copying them over first. But ... but isn't that completely impossible?
Bala also confirmed that despite the new guitar's wacky gimmickry, your old
Guitar Hero III (or
Guitar Hero: Aerosmith) guitar will work just fine, and that "any USB microphone should work." With all these features, Vicarious Visions is going to have to be really creative if they want to disappoint.
I hope this is true for thos avid VC and Wiiware downloaders. Also this game seems be shaping up pretty good.
