Is there any Wii game that can't be done graphically in the past gen?

[brute]

A few years back( in 2008 I believe) I created a thread that asked if SMG/MP3 has better graphics than the games of the sixth gen, ofcourse the opinions were devided, some agreed and some disagreed. But I ask this question once again, does Wii have a game that graphically can't be done in the 6th gen?

I once again have to say yes, I believe Xenoblade, Metroid Prime 3, The Super Mario Galaxy games, Sonic Colors just to name a few have better graphics than anything released on PS2/GC/Xbox.
