Here is my reasoning:
I can sell the Gamecube off to kinda take off a bit (about $50 maybe, unless I can swindle), and the Wii is BC with Gamecube. So it will be like buying a Gamecube++; with added features. Like buying a DS Lite, even though I have a DS. Or buying a slim PSTwo, even though I have a PS2. I hate VC and wish to never support it, and frankly Wii games are shit. At this rate my library will consist of first party titles. As of date, there is only one game I want -- Paper Mario. Zelda, too. But I'd rather play that on the Gamecube -- which is BC on the Wii. Unfortunately Jewtendo decided not to opt to give me a choice to play Paper Mario on the Gamecube, so to be short I am forced to buy a Wii for this game alone... and I guess the other games coming out.
My other option is to just save up and buy a new TV for my 360.
