I went to the Pentax Forum in Shinjuku, Tokyo today to see whether they had a model on display yet. They didn't have one to try, but they had models of all the colours in a display case. The first thing that struck me was that everyone has been blinded by the lights. What a load of fuss about nothing! You can switch them off! Of course these non-functionals models didn't have the lights on and all you can see is an almost unnoticeable black slit going up the front. With the lights out of the way, you can appreciate the design for what it really is.
The straight-on front view seen in most of the photos kind of accentuates it's uniqueness. I don't think it's the most flattering view. In reality it just looks more conventional - like a compact, dense DSLR. In terms of styling, it reminded me of the K-30 more than anything.
The colours looked different to what I expected from Ricoh's publicity shots. They all have the matt "silky" finish that some order models of the K-30 had, not smooth shiny plastic. It makes the actual finish look quite different from the publicity shots from Pentax. The colours are much more subdued and this makes the bright colours look more subtle and tasteful. On the other hand, the brown and grey ones looked almost drab. I was especially surprised that the "Moon Silver" version is quite dark. Unfortunately, it won't match your silver lenses. The ones I liked were both of the blue ones, the white one, the orange one and above all the midnight black, which has a cool lime green side panel.
Finally, some information that I hadn't seen before from a Japanese article:

- Because of Prime M II, the K-S1 has the diffraction correction function that was added to the K-3's firmware.
- The K-S1 is not meant to be the successor to any model. It is a new and unique model.
