It seems to me MFT is a stronger system than APSC. The sensor size difference to apsc doesn't really matter when the system as a whole is better.
As an apsc shooter I feel in limbo. Pentax FF doesn't have the wide to normal prime lenses I want. I'm also not keen on the weight increase, most of my photography is under travel like circumstances and when I shoot I tend carry the camera all day, including meals and drinks. FF mirrorless would technically be quite good for my needs but I really despise EVF's.
There haven't been any IQ improvements for low iso since my K-3 II. Pixelshift, gps, ovf makes the K-3 II the best camera on the market for me which is all good I'm in no hurry to upgrade the body. It's the lenses that are troublesome. The da* 11-18 is a zoom, very expensive and has some characteristics that I don't like. Despite not wanting it I'm considering the lens. Unfortunately the second hand market would mean a huge loss if I don't love the lens. So as I said limbo
I don't know that Pentax is going to be doing a lot more APS-C specific lenses in the short term. My guess is that they will re do the 16-50 and 50-135 lenses with new motors and maybe some optical tweaks, but that may be a couple of years away. Currently, their prime line up for APS-C is the 14, 15, 21, 35 (x2), 40, 50, 55, 70, 200, and 300. Obviously, you can use the full frame lenses, like the FA limiteds, as well and since those are pretty small for what they are, there is not a big size issue. On the zoom side, they have 12-24, 11-18, 18-50, 18-55, 16-85, 18-135, 16-50, 50-135, 60-250, and all of the 55-300 lenses. There are probably a few that I've forgotten, but I guess I think the lens line up for APS-C has pretty decent coverage at this point, particularly if you consider the full frame lenses that are available.
Overall, I think the important thing is for camera companies to build to the market. That is to say, that they release cameras and lenses when the demand is there and release a number that they can sell. I am afraid that Nikon, Canon, and even Sony often build to a market that they wish was there, that is to say, the market that was present a few years ago, and end up having to discount gear considerably to move it. That's probably not important to the discussion at hand, but overall it means fewer camera releases and less frequent updating of models.
At the same time, APS-C definitely has a niche that isn't going to go away and will continue to get support. I don't see any indication that Nikon and Canon are going to be able to hit APS-C prices with their full frame cameras and Fuji has doubled down on their "APS-C is just as good as full frame" mantra with them calling medium format "super full frame" (which is silly in my opinion, because when you factor in lenses it is way more expensive than even mid range full frame).
