What about RAW don't you understand though... RAW is supposed to be RAW, not processed by whatever.
DXO mark is supposed to "measure" the sensor performance, and it does not do that when it can't take into account processing done to make a sensor look better in these tests.

Bollocks! Nikon has been manipulating their RAW output for years, as have Pentax, Canon seems to be the standout here in that they do not. (I rephrased the last sentence due to factual inaccuracy)
You should have a look out for images by the K-5 made by user JohnBee on Dpreview or Pentaxforums, the sensor in the K-5 is an excellent starting point for image creation, Pentax are just extracting the absolute maximum possible within set variables which in turn are set by the industry, i.e. ISO, EV, etc, etc
If DXO mark is supposed just to measure sensor performance then it would have to bypass all manufacturer software and communicate with the sensor (chip) directly. Do you think Canon would hand over the keys to their sensor technology or Sony or Samsung for that matter just so a company can post some stats?
RAW is a file format generated by a combination of available light, lens, sensor, i/o, a/d convertors manipulated by an OS created by a manufacturer to achieve maximum detail at a given industry approved setting, which in turn then is read by various 'Raw Convertors' to display an image.
How they achieve this is up to them. How come you don't get upset about the various ISO settings banded about by manufacturers? Take a Canon 7D for example, its stated ISO1600 is actually measured to be ISO1223. Or Nikon's D300s, its ISO1600 is measured at ISO1114. Now look at the Pentax K-5, its ISO1600 is measured to be ISO1417. Are you saying that Pentax have managed to circumvent the industry standard of ISO, a known variable for example?
Fact is, Pentax have taken a Sony sensor, current generation or next generation (your choice) and used their experience and inhouse capabilities to deliver an excellent image producing tool.
I am seriously looking forward to getting my own K-5 in the next few weeks and combining it with my FA43f1.9, K50f1.2 and FA77f1.8 to create images that I am happy with and proud to share with others.
