Here's a quote that was just put up on GoNintendo. It pretty much goes with what's been said in this thread, and the attitudes of 3rd party developers towards Wii.
“We’ve always hoped Nintendo would get new audiences into gaming with the Wii, and they’ve successfully done that. We also always hoped those people would later buy a next gen gaming machine that does stuff the Wii doesn’t do as well as the others and we can certainly expect that the combination of reducing the entry barrier of the price and making the PS3 and 360 more accessible via Move or Kinect, we will certainly get people who now enjoy playing video games and want to play online or enjoy games in a much high resolution. We do expect quite a few people to do this.” - EA’s European senior VP Jens Uwe Intat
Activision gets a lot scorn, but Wii fans have another 3rd party megapublisher to focus their dissatisfaction with.
