I have the numbers from my old thread (that got me banned) about VGC real 2014 numbers before big adjustments and I can say the PS4 is tracking ahead this year in all 3 weeks until now.
The numbers you are using is the adjusted ones so I would say people should wait a little for the actual numbers to say if the PS4 is tracking ahead or no, because adjustments are to be made (can be both sides though).

where was the main discrepancy last year?  Was it in NA as I suspect?
