If someone cares, here are the numbers for the end of 2013:
http://www.cinemablend.com/games/PS4-Outsells-Xbox-One-Germany-By-150-000-Units-61585.html
PS4: 250k
X1: 100k
Meaning that on average the PS4 sold over 11k per week, while the X1 sold on average about 2,7k per week in 2014 until the end of June.
This could ironically mean that the X1s current weekly numbers in germany are actually too low, since vgchartz overtracking occurred in 2013 not 2014 where vgchartz actually has the numbers a little lower than GfK.
Vgchartz at more or less the end of 2013 (week ending December 28th) as a comparison:
PS4: 249k
X1: 128k
