From the Wii and DS Europe sales press release that was posted earlier:
Wii Sports Resort, the action-packed game that is the first from Nintendo to make full use of the Wii MotionPlus accessory, has continued to generate strong sales, selling around five million* in the five months since its launch in late July.
Nearly half of all European Wii owners also now own either Wii Fit or the new Wii Fit Plus. These 9.6 million*** owners of the Wii Fit range are further evidence that people are enjoying getting fit in the comfort of their own home.
