Well, mostly because games don't tend to sell past the 10 million unit mark anymore, or ever much for that matter.
I mean, it selling over 10 million, and closing on 20 is what should really be celebrated, not a 50 dollar item outselling a 400 dollar item, but thanks.
Wow, your cranky... and you missed the point despite me directly stating the point.
It's a rare circumstance, even rarer then a game selling 10 million, and furthermore it has a decent shot of keeping this up and beating PS3 at the end of the gen. Since it isn't really slowing down much.
Wii play's sales are creeepily linear...
I mean look at it.
