hmm... take a look at this:

and everyone knows that xbox sells like 400 units a week in japan compared to gamecube 25000
xbox leads gc in n. america and that's it, but they are definately in second place worldwide, plus nintendo is actually making money by selling more software, and not at a loss... if anyone quits, it'll be microsoft.. they'll probably not last another losing generation.
