A very detailled and informative review indeed, and published in one of the most respected journal this side of the pond.
I must also say that I always found CI reviews of Pentax cameras to be on the "condescendant" side, they always ended up sounding something like "A rather good camera... for a Pentax...." and I have the feeling that the K20 really floored them by it's IQ.
They also have recently introduced a sharpness measurment that I find really usefull: they give an indication of "global sharpness" (ie edge accentuation) but they also give a measure of "textural sharpness" which allows to see what happens to low contrast details when NR kicks in or at high ISO.
The figures from the K20 are among the best they have measured for APS-C cams with a very good detail preservation up to ISO 1600.
Overall, they pretty much nailed it: best IQ in class (tied with D300), excellent build quality and reliability for a reasonable cost. Only weakness is fast action / sports useability.
Their comparative commentys on the K20 vs 40D/D300/A700/E3 should put a wide smile on Pentax's european execs ;-)
