The breakdown tells an interesting story.
Japan
Wii Fit has outsold Mario Galaxy by an amazing 1.5 million copies.
Others
Wii Fit has outsold Mario Galaxy by about 300,000 copies so far, and is still huge at the moment. Galaxy being outsold by about 100,000 copies per week.
America
Mario Galaxy has outsold Wii Fit by well over 1.5 million, but Wii Fit had a comparitively late start there, and is currently outselling Galaxy by 50,000 units a week (as of the latest figures).
So, if current demand maintains, then in another 5-6 weeks, Wii Fit will have outsold Mario Galaxy by over a million copies.
