If this was shipped by October 21st, then it is safe to assume that more have been shipped since.
Over 1 Million, but the question is how far over 1 Million by the end of the Year?
Edit -
To expand on this, the Wii U is sitting at ~370k sold and the Xbox One is sitting at ~200k sold by VGC estimates. Outstanding numbers for PS4. I wonder how long it will take to pass the PS3.
And I imagine France wont be too far behind. UK, France and Germany could total over 3.5 Million units combined alone by the end of the Holiday.
