What it seems too, is that 1st and 2nd week aligned sales Xbox One was better than PS4 (Xbox One 1'5 mill > PS4 1'2 mill), but after European launch, PS4 is now 1st (aligned sales).
What is obvious too, is despite PS4 launch a week earlier than Xbox one in NA, Sony just sent stock for 2 weeks for November, just like Xbox one. The 2nd one was a waste to have ps4 launch a week ealier and don't coincide with Xbox One NA launch.
So the figure of 18 days for 2'1 million for PS4 is very tricky, and not just because European sales were 14 days later...
