In the sales discussion, Wii is #1. Any talk of 360 being number one should be in the gaming discussion, whether referencing sales or anything else... ;)
Seriously, why is the Wii never counted.
360 has the top total software and third party software for America.
Wii is 100m-53m=47m, 360 131-28= 103. Now I believe this is because third parties think like you do, and don't think about the Wii. They are bad business people and are throwing away potential business by making no compelling software for the average NA "core" gamer.
As a PS3 owner, I think it's pretty obvious why 360 killed the PS3. Price, Earlier Launch, Halo 3, and online experience. I could argue why I bought a PS3, but what I think about the console doesn't matter to sales across the continent.
I would cite regulation, but I know you will simply ignore it.
