Problem is Wii games really aren't any longer than PS3 or 360 games. In most cases they're less feature intensive.
PS2/GC era graphics can die a nice lonely death, but that's just my opinion. I don't really even care about the poly counts, but the image quality is atrocious. These artists create great models and textures and its like taking a big pile of mud and smearing it over them to get them to run on the Wii/PS2. And on an HDTV set, which is what more and more people have? It can look terrible especially games that use a color pallete with a lot of brown or grey in them.
On the higher def systems, the image quality is dramatically higher and you really can see the world create by the developer more or less as it was intended, instead of developers releasing those "bullshot" images so common place during the PS2/XBox/GC/Wii era of console ... basically saying "this is what we intended our game to look like".
