In support of Wii's technical ability, Geoff Thomas, producer at Radical Entertainment told CVG that Nintendo's console can pack a fair punch in the graphical department.
Sure the Wii can do a lot more than we see actually.
I kind of figured the Wii could do more than it currently is. Look at early PS2 games. They didn't look a whole lot better than the later Psone games. We tend to forget that it takes time to learn how to use the tools present.
