The whole point of depth of field is that you can choose how much you want to stop down, but not necessarily how much you can up open your aperture. Choosing good glass is only the start, regardless of the format you are shooting with.
I can only speak from personal experience. I typically shoot landscapes from a tripod and I see a significant different in how much I can push a landscape image with full frame versus APS-C. The K5 was good, the K-1 is a lot better. It is not unusual that I shoot underexposed by a stop or two to make sure that I don't blow out highlights. Whether I can then recover shadows is dependent on dynamic range. You can push any image regardless of the sensor size, but my experience is that when I use smaller sensors, the images start to look "pushed" for lack of a better word. Four stops is an awful lot of pushing for most sensors, even at base iso.
With regard to IBIS, that is neither here nor there. It is present either in lens or on sensor for most formats at this point. It doesn't eliminate subject movement and this is the biggest impediment to using it in high iso situations, in my experience.
I have no idea what will sell cameras going forwards. Maybe you are right, that video is the answer. But even that feels pretty hollow to me. The number of folks who actually own computers and software that can edit 4K video is pretty small. Even HD video pushes my desktop pretty hard these days. The reason Go Pro cameras have fallen on hard times is that people realized that they have a ton of unwatchable footage of them doing stuff that nobody else will watch, except mainly close family members. Video is actually a lot harder than still photography because it takes serious editing to make something that is viewable by someone else.
Almost every smartphone can process and edit 4k video!! Video is almost easier to edit (once exposed correctly at source) than photos. They teach video editing in Grade Four at my kid's school, but Photoshop isn't even offered in the high school!
The vast majority of the photo and video world doesn't not have a home PC (another declining market) and does little to no post-processing, PP fast becoming the "dirty phrase" of the photographic industry, something that turns even core consumers off.
Why do you think most of these cams still have an HDMI out port and USB connectors with slideshows? Most Asian markets do not rely on any PP and go straight from camera to viewing medium (TV, increasingly 4k), with the new intermediary being social media.
This is the same growth mark behind the rise of the DSLR and mirrorless. Try and do it all without a PP "workflow" (the WORST named aspect of this hobby). The reason why Aperture was killed by Apple (caveat: I was a tester for Apple) and why Adobe went subscription is due to the almost total disappearance—in a short period of time—of a middle class, semi-pro user base. This coincided with the near complete evisceration of the P&S camera market. Big, fast glass, has actually become the industry's problem, not its solution.
The reason why GoPro fell on hard times is their market stopped buying the necessary PCs/Macs to keep up with their growth expectations. Now GoPro is thinking that a subscription software model will fulfill their revenue ambitions. Nope. It's the same over-reliance on the inertia of the home PC market.
The number of users willing to push (or even capable of doing so) in post is shrinking. The whole point of many mirrorless is (partly) to remove that step (and Apple is going to help, I might add). The 40 million sales base for dedicated cameras will very soon be 15 million, with a decreasing of those owning a PC to do post.
Chasing shallow DOF is fine, but it can't make a system anymore. But we went though all this in 1984 when AF and reliable zooms came along!
My prediction: Watch for Adobe to raise their subscription rates considerably in the next year.
Even tripod sales are way, way, way down. It's a bloodbath out there.
