A while back, The team behind Mario Kart Wii made mention of a Black Wii Wheel (as well as a Gold one) they had created but not intended to release... Or was it released? The above picture is from a NeoGAF user who claims that he has an official Wii Wheel in black. He doesn't mention where it came from, meaning as of now the likelihood of it being available through retail is low. Hard to deny one fact: That is the Wii Wheel, and it is indeed black!
