That 10% was earlier in the life of the Wii, when it was really hard to get a hold of a Wii and the casualz wouldn't have bothered lining up in the Wee hours of the morning to get one. I would imagine it's higher by now.
I think you have a point, but you're forgetting a third group. Those of us who loved our GC, our N64, our SNES, and our NES because of the excellent 1st party games
Not that I had a NES (too young) or a 64 - my parents didn't see the point of getting a new console when I already had a SNES *tear*
