The numbers cited are from the end of NPD's "May" which runs through June 2 and has Wii at just over 2.8 million in the USA, and 360 at just about 5.6 million through June 2. Vgcharts has 4 more weeks of estimated data for the USA, and makes no distinction for Canada as NPD does. Canada accounts for up to nearly 400k 360s, and nearly 300k Wiis. That means not including NPD estimates for June, North American totals are 3.1 million for Wii, and 6.0 for 360. Add in in the last 4 weeks for the USA and Canada, and you end up at 3.5 million for Wii (80k USA for 4 weeks, 10k for Canada ~ 3.46 million), and 6.2 million for Xbox 360 (40k USA for weeks, 5k for Canada for 4 weeks ~6.18 million). Xbox 360 and Wii have probably an additional 2-3% in sales from Mexico, Latin & South America, and that is how Vgcharts numbers differ from the report ckmlb.
