They may not have written an emulator for the SuperFX. The Wii has enough power, but there is still time needed to make the emulator, and they may not consider it worth it for 7 (NTSC) games at most. (Dirt Trax for example, isn't going to sell as it's primary selling point was the use of SuperFX, which doesn't stand up to even mid 90's 3D.)
