PS4 Sells 5.9 Million Units Worldwide During 2017 Holiday Season, >73.6 Million Sold Through

If it's at 73.6 million as of December 31st, and VGC has it at 71.8 million as of Dec. 9th, then either sales should drop like a rock for the last 3 weeks of 2017 (very unlikely), or the PS4 is overtracked.
