There is no Brain Age on the Wii. You're thinking of Big Brain Academy which is a different franchise (one DS game) and is more whimsical than Brain Age.
Stop looking at Wii Fit as a peripheral and start looking at it for what it is...a motion-centered series of games and exercise that happens to come packed with the balance board that translates those motions.
Also, look at Japan. Wii Sports is not bundled in but is selling incredibly well.
