Although it was never confirmed, it has been rumored that somewhere, a Wii version of Brutal Legend was in development. Now according to anonymous sources, Destructoid reports that yes, a Wii version was in the works, but it's since been canceled due to quality and technical concerns.
According to these sources, the Wii version was in development at Electronic Arts (who will be publishing Brutal Legend), but Double Fine was not in charge of it. If accurate, this would help explain a curious comment creator Tim Schafer told us when we spoke with him back in March. When asked about the rumor of a Wii version, Schafer first looked to his accompanying public relations manager for how to respond, and then said simply, "We are making an Xbox 360 and a PS3 version of Brutal Legend." If, as this new rumor suggests, Double Fine wasn't in charge of the Wii version, then Schafer's enigmatic response was perfectly accurate.

Still, as Desctructoid notes, this is essentially a rumor of what was already a never-officially-confirmed rumor. But considering the reported outcome of the project, it doesn't seem to make a difference -- either these rumors are true and the Wii version existed but was canceled, or they're inaccurate, and no Wii version ever existed in the first place. Either way, it looks like there's no violent, demonic, and comical metal adventure in your future, Wii gamers. Our condolences.
