Both Borgen and The Killing were commissioned for 3 series only, so that is the end of that.
For those with to much time on there hands there has been a recap/blog/ comments on Borgen here:

Looking forward to The Bridge in January (4th I think).
Reminds me I have to sort out ur Scandinavia holiday for next summer. Want to cross The Bridge and probably have a look around Ystad. Without getting murdered in some dispicable way!
