Very interesting, thanks for the link.
I took a quick glance at the DPReview forums a day or two ago for the first time since the K10D review... not surprisingly there's quite some discontent with their review's JPG findings (the common reasoning being "it's working as designed, doing little processing", and blind 100% crop tests have shown people sometimes preferring the JPG over the RAW) but supposedly the reviewer has gone in to defend his findings, which is always good, whether we agree or not. I haven't been paying enough attention to come out on one side or the other... since there's no point in doing heavy research when I'm still several months (at least) away from getting one.
So far though, I'm very happy with everything I've been reading, and have seen some absolutely stellar pics being posted. It sounds like they've really tried to make a camera that is enjoyable and intuitive to use.
I also found a 2007 lens roadmap for Pentax... in addition to the coming-soon 16-50 2.8, 60-135 2.8, and 60-250 4.0, there are more long primes (35mm, 55mm, 200mm, and 300mm), but also a 17-70mm and to finally counter the C/N offerings, a 70-300mm.
I'm not sure how precisely Pentax planned it, but they've managed to do pretty well in the past year by focusing first on price (with the $100 DL rebate), then in-body IS and price (with the K100D), and now with a camera that makes no apologies and has a feature list a mile long. They're still a tiny slice of the pie but they're making good money and they're on a pretty good roll lately. The next year should be very interesting for DSLRs.
Back on to the points that the article made, I do think that Pentax and, to a lower degree, Sony will end up forcing Canon and Nikon's hand in eventually offering in-body IS. By having that plus IS-stabilized long zoom lenses, they could then claim to have the best of both worlds.
More competition will only help us, the consumer, no matter which one we use.
