I've had Pentax SLR's since 1968. I liked the screw mount cameras and the K series.
I was and am very pleased that Ricoh bought Pentax and I think they've done wonderful things with the brand.
I've got a Pentax K10D, K-m and about 10 Pentax digital lenses...all bought new since Nov. 2007. They all say Pentax....although I'm not sure what my new 18-135mm WR...shipping in from Pentax will say.
Eventually I wouldn't be surprised if I get a Pentax K-3. The fact that it says Pentax on the front...and Ricoh on the back...fine with me.
However I do prefer (strongly) to see the camera equipment to continue to be known as the Pentax brand. With 46 years of Pentax ownership...I suppose I'm a Pentax brand loyalist.
