I haven't really thought about it, but Wii Play could easily top 50m lifetime the way the Wii is selling. This is assuming the Wii sells around 150m lifetime, and Wii Play get a 33% attach rate, which isn't unreasonable.
As for the other two, I could see them both doing 25m or more. They are currently outpacing Wii Play and have vastly outpaced Nintendogs, which is currently at 20m, and they show no signs of slowing down. Last week alone MKWii sold >400k, and Wii Fit sold >580k
