from NPD we know is selling around 15000 per week in the USA in August, and we have the numbers from mediacreate for Japan. In a few weeks we should have the info of how much it shipped in july, august and september. That should give us some idea of how much it has been selling per week worldwide, imagining that for evrery wii u sold to the public retailers asked for 1 replacement to be shipped to them.
