He is not refusing to believe the Wii's success. His points are entirely valid.
Successful marketing of a novelty product does not constitute a revolution, and casual gamers will not remain for the long haul like the hardcore. That's just common sense.
It's a good thing that not all developers are blindly following the money. It shows they have a little thing called integrity.
I like how you think it's not okay to for developers to blindly follow the money, but then it's okay to blindly ignore Nintendo's succes. It's good to diversify, they'll be in a lot of trouble if they put all their eggs in one basket.
Your second paragraph is hilarious. When did that become common sense? I just told my co-worker that and he said "What the fuck are you talking about?"
Novelty product? Are you still in 2006? I see you yourself does not believe in Nintendo's success, maybe you should look at their financial reports and compare them to Sony's and MS's.
