Unreal Engine 3 Coming to Wii

Unreal Engine 3 is to be ported to the Nintendo Wii, but not by who u would expect. Epic's Vice President Mark Rein has repeatedly said that they would not port the Unreal 3 Engine to the Nintendo Wii. The Engine has been known for great games such as Gears of War and Rainbow Six:Vegas. This Engine will be ported over by an unnamed licensee.
He said, ""It's their own port, in the same way Ubisoft brought Unreal Engine 2 to the Wii (Red Steel). I just don't see a big market there to bring this big hulking memory intensive engine over to a much smaller system."
Now the only question is how much better will the graphics be. Obviously the Wii isn't the powerhouse that the 360 and PS3 are but is it possible for the graphics to be substantially better than the graphics for earlier Wii games (you better hope so)
