The price (within rational limits, of course) doesn't matter to me. If I want a given console, I'll get it. Besides, buying the accessories is where we overpay. It would be nice if the Wii could also play CDs and DVDs, but that's not necessary. I do wish the console's disc drive were top loading, though. I've always disliked slot loader designs, but that's what everyone is making these days.
Anyway, once (if) the black ones come out, I'll immediately get Mario Kart Wii, Super Mario Galaxy, and Metroid Prime 3. That might be it, until a Zelda game comes out exclusively for the Wii. I might be tempted to get the Resident Evil games ("The Umbrella Chronicles" and "The Darkside Chronicles"). Normally, I don't have any interest in the RE shooter games, but these two include some important parts of both the Chris and Leon stories, so I might have to get them.
