My take?
Some people need to stop being so damn ignorant and realize that presentation is a very important aspect of video gaming. Draw in has always been a problem with gaming but as we get new hardware it becomes less and less prevalent.
Another major falw i've already encountered with the wii is being able to see items of importance off in a distance, there just aren't enough pixels at 480 to draw something distingusihable.
The lack of better presentation is going to hold the Wii back with both the casual and hardcore crowd. I'm not saying it'll kill the Wii, just that it's gonna make things harder for the Wii.
Personally i think adapting traditional genre's the the new control scheme is gonna do more to limit the wii then the graphics.
