I don't think that these 3rd party games, like Madworld, have any business strategy, as Nintendo has.
They are just making hardcore games for the Wii, but it won't make them accessible for the New Market, only to the hardcore gamers who has a Wii. It will be very popular on forums like this one, but it won't be a system seller.
If you believe that upstreaming means simply starting "casual" and making "more hardcore" games, you are wrong. There is also a change between the Old Market and a New Market:
Nintendo's strategy is NOT about getting enough money from "casual" games, and later making a more advanced console, and more complex games for the "hardcore".
It is about upstreaming their current, "casual", New Market audience, and make more advanced games for THEM.
