Any camera can be, and is, used for pro work (plenty of people using the Kx/Kr etc.). No manufacturer markets their cameras as semi-pro. Just because Nikon/Canon have a wider range of cameras which introduce different features at different price-levels, doesn't make the K5 a top-line camera (I know you are not saying that) because it's better than some of them. Some magazines categorise the K5 with the 5100 !!
Yes, the K5 is 100k, the 5DII is 150k and the D800/D4 is 200k.
That's fine - call it whatever you want (i like semi-pro, because when I get that camera, i'll be a semi-pro!)
However, price levels and features - the k-5 matches the D7000 and the 7D on most fronts. Price, 1.5k MSRP, give or take. Features, pretty much the same. The k-r/k-x matched the going equivalent of the entry levels of that time also, in price and features.
Of course, I don't consider the k-5 (or the D7000 or the 7D) to be a top of the line camera. And your discussion with LamyTax became little bit silly, in my opinion, because it's become a argument over a minor point (midlevel vs entry vs whatever the k-5 is).
Again - my understanding is that all the shutters are rated at 100k minimum, and only the top level pro (full frame) cameras are rated at something else (higher). I don't believe there are cameras rated less than 100k. I don't think it's such a big deal for the D600 to be rated at 100k - although if Nikon had a APS-C camera with more than 100k actuations rating, then it would have been a stupid decision. As of right now, it's still an upgrade from APS-C cameras in other ways.
The K-30 really breaks some serious ground, being priced at the D5100(D5200) and the T4i level, but putting out features that surpass the D5100(but maybe D5200 will compare) and the T4i. I hope that the k-3 does something similar.
For what it's worth, Wiki puts the 7D into the Prosumer Range (above midrange), while they put the D7000 into the Midrange (above Consumer range). And they don't give the k-5 a defintion
