The current K-o1 mirrorless and K-mount APS-C camera.
The Chinese Fengniao editors interviewed the Ricoh head (source RiceHigh). And they once again confirmed that:
"Our development team is still working on it and the project is not aborted."
Doens't sound really promising when you say "is not aborted" :) That said a while ago an anonymous source told us this:
"Pentax's new fullframe "might" be a mirrorless, using a newly developed hybrid mount that accepts current K-mount lenses and adds the ability to use newer short flange lenses as well."
Now let's see if something will happen. It's about time after 5-6 years of Pentax FF rumors floating around the web :)
