@snaffles:
I (still) don't have a Pentax and I have no "real" decennial experience on photography but I learn that to make a good shot you have in the right place at the right time... this is a commonplace but this is currently true. Take
this one or
even this of my shots... it's made with my Fujifilm S5500 with a close-up lens... should it demonstrate that I don't need to upgrade my camera? (I bet I will not take such a shot in a year after I'll purchased the Pentax...)
I think you were talking about the dpreview challenge when you say there's no made-in-Pentax winner shot... if I look at that photos I don't see anything you couldn't do being in the same place at the same time with a Pentax (or any other today DSLR)... maybe you couldn't do the same with a compact camera (BTW did you notice how may compact camera shots where placed in the first 20 positions of each category? Are compact camera being as good as DSLR?).
Now, if you look beyond the first placed position, you can find for example that in the 9th position you have a Hasselblad shot: do Hasselblad owners think that their camera is good only for B&W shots? Also, looking beyond the firsts place you can find also Pentax shots (example: 3rd place candlelight portrait is a k10d... honestly, is that worst than the 1st placed?).
So, IMHO you should not focalize on who wins... as said it's statistically easy to have a Canon or a Nikon and not only because of the majority of the their owners, but also because the voters (who should own a camera... reflecting the same market share) are always a bit biased in favor of their owned brand/model.
I was about to choose a Canon because also my friends have it... now I changed my programs in favor of the k200d even by giving up the live-view (which was fundamental for my macro shots...) that Canon feature only because of the Pentax CCD sensor colors. According to the dpreview challenge results I should give up the k200d... or back to film cause a Pentax 67 placed second on the "tables and chairs" category?
