The market may be growing but it is 1/3 the size of the DSLR market with twice the competition. Once the market is mature in terms of EVF tech (cheap parts) they can always drop an EVF into a KS1 type camera with K mount. They are probably better off waiting till the market shakes itself out first.
The K-S1 with an EVF instead of a mirror, but the same mount, would not have the size advantage you'd get from proper mirrorless and new special for mirrorless lenses. And if you're late to the game you're late, and people will reject your camera because there are no lenses to go with it.
@Winder: Olympus and Panasonic have historically not been competing. They are now. Olympus is pouring in resources to improve the video functionality of their cameras, looks like people just bought Panasonic cameras over Olympus ones because the Panasonics are so much better at video. Olympus is working with professional DoPs to improve their video functionality. They want to target filmmakers it seems.
@Kunzite: A SR system that works well enough for FF (think the system in the A7 II, which isn't really fast enough) will work even better with an APS-C sensor. It will do wonders. And if they use exactly the same system, the amount of stabilization will be amazing, especially in video (if they chose to use it). An APS-C camera in the body of a FF camera might also fill a nice niche, photographers can see what is going to enter the frame soon, so they get the timing exactly right. Though I doubt Pentax is going to do that. But they could, and it would be rather innovative.
I still like the idea of a hybrid viewfinder in a DSLR. I think I'd be willing to give up on mirrorless if I could have that... yes, it would be a bit bigger and heavier, the lenses would be a bit bigger, but having an OVF when I want it, and an EVF when I want that instead...
