Just view the above album and you can find them all! Outdoor and indoor, low ISOes and high ISOes, including 6400 shot (an example here - Warning: Large file, click will download!).
Well, what I would say I am not impressed with those samples. Colours are odd and many of the images are not sharp (blurry and with low resolution). Moreover, purple fringing has now come back as a more serious problem, see this example (Warning: Large file, click will download). I just hope that it is just owing to the "user's errors" or he is just a really "bad photographer" (as those defensive but offensive Pentax fanboys always talk about and I'd better use their usual terms! LOL..). But anyway, I think it is unlikely to be the case. It seems that the IQ of the K-x isn't that great at all, so far from all those full-size original K-x sample photos that have been posted.
But one thing is for sure, the noise control of the K-x is excellent. Just see how little noise the above 6400 shot is. I am sure it will blow the K-7 out of the water too easily in this regard.
As far as other IQ aspects, I am afraid that the K-m should be far better. So my humble recommendation is that if you just want a *Pentax* DSLR as a photographic tool, get the K-m now as the price has started to drop and as long as the remaining stock lasts.

The only way to do it is to compare shots from two or more cameras taken under the exact same conditions (light source type, intensity, direction). In addition, to get a good picture of the actual differences one need to test both Auto and Custom WB.
To make such comparisons, just use dpreview.com color comparison pages, such as this one:
http://www.dpreview.com/reviews/pentaxk7/page19.a...
If you go over ALL Pentax DSLR's to date (from the *ist D to the K-7) you'll see that not even ONE camera trails the competition when it comes to color rendition. Do you actually think the K-x is going to be the first to produce "odd" color? I'll be happy to wait for their review and revisit this post. It would be fun to prove you wrong once more :-)

As for the K-7 greens, please specify which APS-C camera you think is better and I'll be happy to go to the page I linked above and compare the two using my calibrated screen (btw, is your screen calibrated?)
And just so that I can understand your color preferences, do you prefer the greens of the Canon 50D:

> DPR do post samples.
Of course they do, people want to see them. By the way, have you looked at dpreview's K-7 samples? ;-)
Anyway, these samples can't be used to claim that a camera has better image quality than another. This is what the studio shots and lab tests are for.
> Were all those samples taken in the "same conditions" at same places and at the same time?
Again, they don't need to. This is what the studio shots and lab tests are for.
> What's the value of those samples then?
They are fun to look at. It would be very boring to only see the same still life shot over and over again. However, one can't reach any serious conclusions about IQ from these samples.
> Boy, just don't mix up picture samples with lab test results!
I don't mix up the two. You do. You're the one claiming to be able to reach conclusions about the K-x IQ from random shots taken by random people under changing conditions.
> And, my SpyderPro calibrated netbook screen is worse than my factory calibrated professional grade EIZO in colour accuracy. So?
Most likely both are inaccurate. The Netbook because its panel is incapable of displaying accurate colors even when it is calibrated; the EIZO because you didn't bother to re-calibrate it. Let me tell you a secret: Screen calibration is an on-going process that needs to be performed again from time to time, it's not a one-off thing.
Oh, and you failed to answer my challenge. Here it is again: Please specify which APS-C camera you think has better color rendition than the K-7.
I also assume that your lack of reply to the 50D/K-7 comparison means that you concede that the Pentax is magnitudes better than the Canon, as everybody could easily see.

In this case, I do not know which lens the photographer was using.

take a look at the pics in this article

click on the pics to get the uncompressed copy, the IQ of K-x is really good
though I have to admit the color rendition is a little different
