I'd rather not buy several switchboxes to hook up all my systems. :

Alot of the reason I like the Wii. I don't have any previous Nintendo consoles, but if I did, I wouldn't want to have to move my TV off my wall in order to hook up a previous system. I have My PS2 and Wii on a 3 way switchbox right now, since I still play GC and PS1 games regularly, I'm glad I don't have to rewire everything, like I would if I had to use a GameCube or PSX.
So, yes, I would like BC. I bought the Wii over the PS3 because I viewed it as buying 2 consoles, a GC, and a Wii, as well as all the VC games. If I didn't have a PS2, I probably would have got a 60g PS3 way back when they were BC, because that would be like buying 2 consoles for me.
