These numbers are tough to reconcile with VGC numbers since VGC likely has errors going back to 2012.
For example, VGC has 2012 at 3.818m. Up 5% would be 4.009m. That would leave around 900k hardware unaccounted for in 2013. Considering PS4/XBO were said to be around a third of the market and those only sold 894k, I doubt the total is over 4m.
