The Japanese Gamecube games are region-locked and will not play on a US Wii or Gamecube system. And I agree, the going rate for Dance Dance Revolution is outrageous. I did some checking and I haven't seen any news on a DDR release for the Wii but given the popularity of the dancing games and the control-style of the Wii, I'd still think it would be a game that we'll see a release for on the Wii at some point. If I see any news I'll email you and let you know.
