My main questions would be if you're matching the time frame correctly, and whether your factoring in that VGChartz includes data for Canada ... Quite often NPD has odd week overlaps ( a Week in October may be reported in their September data) which could (easily) account for the loss of 100,000 units; and Canadians could account for 50,000 XBox 360 systems sold.
