Unless I'm reading things wrong VGChartz has it at 18.2m with one more week to add so pretty good tracking.

VGchartz: 18.2 as of December 20th

Real numbers: 18.5 as of January 4th (source)

I wouldn't call that good tracking, especially considering Christmas.

I don't understand.  How is this overtracking?

Unless PS4 sold only 300k during December 21st - January 4th (which includes Christmas!) it's overtracked, and it's been selling 750k to 900k the last 3 weeks according to VGChartz. Overtracked by a mile.
