Call of duty4 graphics. Sorry no way. Yes God of War looked amazing for a PS2 game and similar enhancements are possible but I doubt there is much room for the Wii above current Nintendo First party titles.
Why? Because it is essentially a faster Gamecube. The devs know most of the tricks already. This made it easier in the beginning but it also means that there are no huge untapped reserves available.
The modern Nvidia and ATI cards in PS3/360 simply are one or two magnitudes faster.
