The K-7 has a new sensor with claimed better high ISO and less noise in RAW.
Seems to me that you are making the misstake of judging the performance by the K20D instead of the K-7.
Quote: AF (Multi-CAM3500 = 51-point, 15 cross-type + Auto-focus tracking by color using RGB AE sensor) - AF-C is way better, AF-S - I hope that at least that will be on par
How do you know that the AF-C is "way better"?
The new AF system in the K-7 also has a colour sensitive sensor that improves low light focus and also tracking ability.
Quote: FPS - more
Very marginally more.
Quote: 12 bit raw and 14-bit raw
Not something you can detect in images.
Quote: lossless or lossy compression in raw
Now you are listing the K-7 features and claims they are for the Nikon.
Quote: shatter lag is less
Yes, it is less for the K-7. K-7 is faster than the K20D.
Quote: Flash system support/control external flashes - way better than Pentax can (and will) ever (unfortunately) offer
You are trolling. The K-7 has new P-TTL and improved performance over the K20D.
Quote: Flash X-Sync: 1/250 sec (up to 1/320 sec with reduced guide number)
Only a minor difference, and the K-7 has flash sync up to 1/8000 for high speed sync flash.
Quote: viewfinder - better (100% @ 0.94x vs 100% @ 0.92)
Both K-7 and D300 has 100% viewfinders, so?
Quote: lens mount includes a mechanical AI aperture ring connector
Pentax K-7 really takes advantage of the A-serie manual focus lenses from 1982 and newer and they work in all exposure modes even the automatic and semi-automatic ones. When was AI introduced?
Quote: Nikon users (I am not) will be able to list much more small details like you did for K-7...
So?
Let's see some things you missed.
The K-7 has rotational sensor, which means automatic leveling function and straight horizons.
It is fully weather sealed with guarantee for cold climate (the D300 is not guaranteed to work below 0 celcius).
The K-7 is almost half the size of the D300.
K-7 has two HDR-functions.
K-7 read the MTF-chart from the lenses and adjust exposure after the best lens performance, but can also do correction for distorsion and lateral CA.
K-7 has TAv and Sv modes and easier and more programmable ISO functions.
HyperProgram of the K-7 is still something missing on the D300.
