Wii U did ~580k in December. VGC has it at 545k. Under tracked ~35k

545k for 4 weeks of December. There are a few more days in December to make up the extra 35k. Yarp

The retail calender runs on a 4-4-5 week system. December was 5 weeks covering November 30 to January 3. VGC and NPD both report for that period.
