Rumours are circulating that a whole swarm of Michael Jackson songs, guitar orientated or not, will be released as DLC for Guitar Hero. There has been a leaked video of Billie Jean running under Guitar Hero: WT on YouTube, but was taken down due to a copyright claim.
Billie Jean on a motherfucking guitar? I know they have the license to MJ's provisional library (example, Beat It, suitable choice), but milking over his death like that? Nahh... Get into Rock Band before the milk grabs you.
