Haven't seen you for a while, Kwistenbiebel... Good to see you again...

Any improvements in the pipeline (KT2008), regarding the 'biased' render methods and the physical sky ?
Regarding the physical sky, I know what you mean (something about adding ozone - right??), but we haven't put any efforts in this for KT2008... 
I suggest that you use HDRI-probes, which - in addition - will make your exterior renders more realistic... 
Regarding the biased render methods, you'll see a combined MLT + BPT preset and most of the render methods have been fine-tuned and optimized... 
But apart from these, you will see many other improvements and enhancements...
Perhaps the Mac port being the most important...  
But also the new Material editor, the instancing brush, the networking feature, Grouping feature, IES lights, and much, much more...!!  
I've just made a quick render with some Xfrog 3D trees, which users can insert very easily from the models menu and subsequently populate using the instancing brush... 
Nothing fancy... It only took about 10 mins to set up and 15 mins to render...
