There are many reasons why you are not seeing final firmware photos. While Pentax has undoubtably reached a Firmware 1.0 release candidate, they have to perform QA and regression testing of the code before releasing it into the beta-test community. This is to make sure that they haven't broken something else in the code while tweaking image parameters, etc. This is standard software QC practice.
>What is with this pre-production firmware? What can be improve at the last minute? I don't believe they still working on this camera.<
NASA frequently works on their planetary probe software up until the last minute. In fact, some probes are launched into space toward their objective without anywhere near final code, and the finished code is uploaded to the spacecraft only when it is about to approach its target. Now THAT takes cajones
You'll see release firmware photos in the next few weeks as soon as the update passes internal QC and is propagated out to those who have test cameras.
