I just asked the same thing out loud while reading it and my brother piped in that it was also sold separately and that he had to buy an extra copy because his was stolen by a friend. Surely it didn't sale 6 Billion worth without being part of the Wii bundle.

Also, I wonder how they calculated the revenue for Wii Sports since it was packaged with the Wii. $6 billion seems like a lot.
