Originally posted by Kobie I believe so. New AF system, (possibly new IBIS), Hybrid Viewfinder all lead in that direction to me. But it all comes down to if everything works reliably and seamlessly.
Canon is apparently working on a version of Hybrid DSLR (new 1 DX), Nikons D780 is a hybrid DSLR, so it would make sense if Pentax followed.... I mean surpassed them with their hybrid system (which based on the patent info, it would).
You seem to be using two terms here. Firstly a
hybrid viewfinder, which means an OVF that can become an EVF on demand as desired. I personally think this is rather unlikely for the new APS-C camera. About a year ago Ricoh development staff mentioned in an interview that a hybrid OVF/EVF was difficult because it degrades the quality of the OVF. Imagine a hypothetical camera that has an OVF only 85% as bright as its predecessor, but could switch to EVF mode. I wonder how many users would be comfortable with the compromise, especially since it would be more expensive. Most people who have a preference for EVF are moving to pure mirrorless anyway. I think this is the main reason we haven't seen a hybrid viewfinder from any manufacturer yet. It's a question of marketability rather than technical feasibility. Sure, if all else was equal, you would prefer the flexibility, but not it imposed a compromise on something you care about more.
The other term you use is
Hybrid DSLR, and you seem to have a pretty loose description of this. Even the D780 qualifies and I see that as a mild DSLR update. I think it is almost certain that the new APS-C will include some new technology to make the camera more content aware during focusing and display more information in the viewfinder. In particular, I think eye AF is a must feature now and the new Pentax will deliver this through better sensors. I'm expecting a much more intelligent AF system because of multiple comments from Ricoh employees about deep learning and so on over the years. We could also hope for some interesting new manual focusing assist tools, but I'm less sure about that.
