Since last night's test was a bit rush. Tonight I did a similar side by side test again between K-5 and K-01. Just for a reference, I also added Panasonic G3 in the test so I'd see how a smaller sensor compares w/ the bigger APSC sensors.
Here is the testing setup:
1. indoor w/ ceiling light (a bit brighter than last night one so to help w/ manual focus), also around mid night to avoid light changes
2. tripod: Gitzo 1540, ballhead: Markins Q3
3. K-5 and K-01 had FA31 mounted, G3 had Panasonic Leica 25/1.4 on
4. both high ISO noise reduction and long shutter speed noise reduction were disabled on all cameras
5. all lens adjustments were disabled if there is an option there
6. D-range highlight/shadow correction were disabled
7. manual exposure mode was used on K-5 and K-01 so to keep the same exposure settings on both camera , Av mode was used on G3 (the camera has pretty good auto exposure in Av mode, and it's not a priority in this test, so I just let the camera do the job)
8. all cameras set to auto white balance (tried manual white balance, can't get any better colors than auto ones
)
9. manual focus was used on K-01 and K-5, w/ focus peaking enabled on K-01 (enlarge 6x w/ FP), used live view w/ 10x zoom to help manual focusing on K-5. A few testing shots were taken and reviewed (enlarged to 16x) on back LCD screen to verify the focusing just to make sure I've done the best on focusing. Auto focus was used on G3 (again, this camera w/ PL25/1.4 just never fails on AF)
10. K-01 and K-5 were set to wireless trigger w/ 3 second timer, G3 was set to 2sec self-timer
11. aperture was set to F5.6 on K-01 and K-5 so to get more DOF and reduce the impact of focusing error. G3 aperture was set to F4 (which is probably the sharpest aperture for PL25/1.4 lens)
12. tested both in JPG and RAW (G3 only tested in RAW), ISO setting:100 (K-5 and K-01 only), 200, 400, 800, 1600, 3200, 6400, 12800 (K-01 and K-5) and 25600 (K-01 and K-5)
From what I can see on my screen, the test results are pretty inline w/ what I got yesterday: photos from K-5 are a tad bit (1/3 to 1/2 stops) brighter than those from K-01 at the same setting, and again, K-01 photos seem a bit sharper (I've tried my best to focus properly on both cameras, and the AF results from K-5 under such light condition just can't compare w/ what I got w/ manual focusing in live view). High ISO noise evel is about the same, except at ISO25600 which K-01 isn't as good as K-5. I guess it's because ISO25600 is the extended ISO on K-01 while K5 ISO can be extended to ISO51200.
High ISO from G3 obvious loses to K-5 and K-01 in details and resolution, especially at ISO3200 and 6400. But it's pretty close or even slightly better at lower ISO (at least to my eyes). I guess the smaller 2x crop sensor isn't too bad at all.
Enough talk. Here I've uploaded all the original files on 4shared. I think you need to register an account (free of course) to download them. It's a free account, I don't know if there is any bandwidth limit. Sorry I can't find a better way to share such big files. File names are very obvious, you won't make mistake w/ the cameras and ISO settings on each photo:
4shared - K5vsK01 - shared folder - free file sharing and storage
There is a video file in there too, probably too short and too badly taken to show how capable this new camera is as a video camera.
Hope these can be some help to some friends who are interested in this new camera.

Edit: I think most guys here don't really bother downloading all the original photos. Here I made some crops of each photo taken by every camera. The first one is center crop, the second one is crop of the right side. The sequence would be K-5, K01 and G3. All photos were converted from RAW by CS5 RAW Converter at default setting.
Here is the testing scene, taken by K-5, K-01 and G3 respectively:
Here are the center and right side crops:
ISO100, K5 and K-01
ISO200, K5, K-01 and G3
ISO400, K5, K-01 and G3
ISO800, K5, K-01 and G3
ISO1600, K5, K-01 and G3
ISO3200, K5, K-01 and G3
ISO6400, K5, K-01 and G3
ISO12800, K5 and K-01
ISO25600, K5 and K-01
