K-01 ..... RIP ..... ?????? K-02 Who would buy one and what would entice you?

I agree.

The K-01 is a Hoya-era model, so I imagine as a Ricoh-era model a K-02 would incorporate Ricoh tech.

To start with, the twin phase-detect sensors of the GRD IV. Ditto the snap focus feature. MODE 2 focus-peaking. Heck, the whole Ricoh GUI.

These can all be implemented right now to release a K-02 tomorrow. Unfortunately Ricoh is just as bad as Pentax when it comes to video, which is an important feature for any liveview-only camera, so they'll need development time to overcome these shortcomings, especially in-video focus-peaking for me.

Anyway, in my opinion, the K-01 isn't a CSC and was never meant to be one so it was never going to win any comparisons against CSCs when it comes to size. It is a DSLnR (non-Reflex) to use SLR lenses. With only the K-01 as its sole member so far, it's hard to see it as a separate category though in itself at the moment. But it's inevitable Canon and Nikon will release their own DSLnR models eventually purely for cost reasons (hence likely entry-level) so this category should become more defined.
