I agree, the Wii version should be able to stuff more substance into the game. However, whereas the DS version can get away with multiple copies per household, multiple copies of the Wii version in a single household just doesn't make sense.
Now whether a more substantial game can entice more people to buy or whether there would be a more significant reduction of copies sold due to the nature of console games is still up in the air.
