Still a bit of a rumour at the moment: Guitar Hero World Tour will have downloadable content for the Wii, we all know that. But if you've gone and squandered all your memory on Virtual Console games, then you're not exactly going to be too happy about the prospect of clearing it out. WiiFanBoy is reporting that World Tour will save downloadable content directly to the SD card. As well as this, you'll apparently be able to play songs directly off it.
Interesting if true!
