He's comparing the top 10 selling games on the gamecube to the top 10 selling games on the Wii, then saying, "look, it's mostly Nintendo."
Another way of saying that is by saying, "only two third party games on the Wii managed to sell more than 2 million units. That's not to say that others weren't wildly successful, but the to reach the top 10 on the Wii is very high."
There's really no reason to argue about software sales, because anyone can spin them any way they want. The *fact* of the matter is that developers and publishers will find ways to make money. They're good at that. And they'll publish games on the systems that sell.
If the Wii isn't selling software, third parties will duck and run from it. Don't you guys see that happening already with all of the software project cancelations on the Wii? It's hopeless. The system is dead!
