I'm probably not going to sell my gamecube when I get my wii because i'll only get like $5 from it, but I'm going to play all my gamecube games on my wii. My gamecube will most likely just sit there and collect dust unless I just feel like playing it for some reason (I have no idea why I would do that.) The wii is always going to be plugged into my TV, so it would be a hassle to connect the gamecube up every time I want to play a gamecube game.
