I'm surprised everyone has remained so civil. Well done all.
The answer is obviously no. It is not technically possible for the wii to have graphics anywhere near the quality of COD4. The difference in pixel-pushing power between the wii and the PS360 is far, FAR greater than that between PS2 and Wii.
You won't even see as big a leap between early wii games and late wii games as you did with the PS2. Like it's successor, the PS3, the PS2 embodied a "performance over programmability" ethos, and it therefore took many years for programmers to take advantage of its complex architecture. In hardware terms, the wii is very similar to the gamecube, so expect to see similar graphical advancements between games at the start and end of the generation as you did with the GC.
