Life is too short to deal with things that irk you on the internet. It is probably better to ignore fellow Forumites that aggravate us then to get into flame wars with them.
Often the issue is with phrasing and it does feel as though the OP is a bit inflammatory. "When will Pentax catch up..."
Of course, your perception of Pentax depends on your needs. To me, they are one of the best still photography companies out there. It may be that still photography is passe at this point, but I still enjoy it far more than video. I do shoot video of my kids and such, but for the most part it just ends up on hard drives to languish. Honestly, I am not a big fan of shooting video with SLRs either. The issues are as much ergonomic as anything else and no, the experience of shooting video with a Nikon D5600 isn't very much different from shooting it with a KP or K3. It may offer a few more options with video, but it doesn't offer 4K video or many of the other features that are offered by mirrorless cameras. In point of fact, Panasonic and to a lesser extent Sony are the way to go if you want ILCs that shoot video and Nikon is trailing pretty badly at this point.
Each camera maker has things that they do really well and other things that they don't do quite as well. Canon and Nikon have lens line ups that are unmatched by the other brands. You may not need all those lenses, but they are there. Sony has mirrorless full frame. Pentax has tightly made, ergonomic bodies that offer weather sealing for less than you can get with other brands. Features like pixel shift and astro tracer can allow you to get close to medium format quality with much smaller sensors. Shake reduction gives stabilization to fast primes -- something that only Sony and Olympus offer too. Obviously there are plenty of areas that Pentax can and will improve over time, but I still am convinced that they offer some of the finest shooting experiences out there right now.
I wouldn't encourage the OP to sell his gear, but more evaluate the things that are important to him and things that he truly needs. It may be that the best thing is to add a Panasonic camera for video purposes if that is really important. I don't know that Nikon is the way to go for that though. Either way, welcome to the Forum. We are a friendly sort and if we seem a bit upset by your introduction, we have met a few too many trolls along the road.
