I agree with you BellaKazza, Also with GameStop (and most all other retailers) getting rid of all the GameCube games it's not like anyone who is going to be going out and buying a Wii at this point will have access to any GameCube games to play anyway, and if they have GameCube games then they most likely still have a GameCube too.
Backwards compatibility was a nice feature at the start but as the generation goes on it becomes less and less a big deal. At this point Anyone who is buying a Xbox 360, PS3 or Wii are not thinking about ANY of the previous generation games.
Personally I don't even play GameCube games on my Wii, I still have my GameCube hooked up, and I mainly do this for the fact that Some GameCube games actually look better on the GameCube then on the Wii.
