Well I was over at the Guitar Hero forums, ya know browsing it. And some fellow who claims he got the game early said the wii update actually did activate the DLC for GHWT. He didn't post any vids or pic, but I have to say I believed him. He posted the sizes of the songs too and none of the songs exceeded 187 blocks. He said at first he couldn't access the DLC, but then he performed the system update and it allowed him to get to the store. So maybe Brandogg is right, that's saying the poster is telling the truth.
