In theory the power difference should mean Wii would have much better graphics, but in practice, few developers actually push the Wii so a lot of Wii games tend to have PS2 or sub-PS2 standard graphics.
Also, a lot of developers pushed the PS2 over the past 7 yrs which is why we have games like God of War 2, SoTC and even MGS3 that are comparable and in many ways superior (in graphics) to the vast majority of Wii games.
