The main issue with your argument is this: Mario Kart Wii is a multiplayer game, in fact it's even an online multiplayer game with endless replayability while Super Mario Galaxy is a one player game as is Wii Fit, both of which are being improved upon/added to with their respective follow ups.
This is why you won't see a sequel to Super Smash Bros. Brawl on Wii either, they're both enough for the one generation.
Another thing is the Wii Fit you know now will not be sold any more once Fit Plus hits. Wii Fit Plus w/Balance Board is going to replace Wii Fit and the Wii Fit Plus software will also be made available to those that bought the original. A few people have been confused with that so I thought I'd clarify :P
