In many ways, I admire Pentax as a company but the digital camera market has not been kind to it. They don't have the resources as the bigger camera companies do, but always managed to introduce interesting products that appeal to photo enthusiasts. Not the best specced, but balanced and usable at a fair price, like the K-1 full frame.
I expect the K-1 to sell well at this price point. Many Pentax faithful will upgrade, no doubt, and many others will be drawn to this camera for its low price and good features. I think Kajiwara-san would be most pleased.
