The platform holder revealed today that European Wii sales hit 30 million units in the week ended December 25, 2011, but it wasn't exactly shouting about it.

This figure comprises 22,663,321 bundled with the original Wii Fit software and 9,451,107 bundled with Wii Fit Plus software. Since breaking the record, Nintendo has now sold over 22.67** million copies of Wii Fit and more than 19.31** million copies of Wii Fit Plus worldwide.
