There's never going to be a Wii Fit 2. It goes against the Nintendo business model this generation.
The Wii Fit market doesn't care for sequels. They're not used to the entire 'buy the same game again next year, with like, 3 new features' business model, and they don't spend enough on games to justify spending another 80 bucks on Wii Fit. Not to mention the fact that Wii Fit, despite being a year and a half old, is still outselling every other game except Wii Sports, which is a pack in that you have to buy to play Wii Fit anyway.
They might release something along the lines of Wii Fit: Get Connected!, which would be a series of free minigames released via Wii Store, but they'll only do that if the sales start to lag and they want to advertise something new.
Wii has more 20 million sellers than PS3 has 5 million sellers.
