I don't look at reviews, I look at what I experience. I shot the K1 for close to two years. I wouldn't discount the half second faster focus. It opens shooting opportunities, allowing you to capture shots that you couldn't otherwise. I didn't bother shooting birds in flight with the K1 because the results were poor, and I get those shots now with the Mark II.
The K1 is amazing in low light. I would be constantly amazed by what I was getting at high isos, and was probing the limits in the different shooting situations. Noise isn't linear; it depends greatly on how the photo is exposed, the color and brightness of the subject. In some situations a high iso and high shutter speed will get better results than low shutter speed and low iso, other situations the opposite. So a review with a couple shots is meaningless to me. I want to see over a range of shooting situations and subjects where the limits are. I'm finding the Mark II has higher limits than the K1, with a dramatic falloff when the conditions don't fit. I'm already getting shots that I wouldn't have gotten with the K1. These are extreme conditions with low light. Oddly those conditions produce awful images as well. The boundaries have moved, and it is up to me to probe the limits. So far they are further than the K1.
I wouldn't diss the dynamic pixel shift unless you try it. I have processing software, it is free and works well. The function is surprisingly useful, again in extreme conditions. These shots could be taken by other means; a tripod with long exposure, a tripod and four shots stacked post. What I do typically is have my long lens on the body, with a tripod and gimbal sometimes, and a shorter lens in my pocket. The gimbal doesn't work well for short lenses, so if I see a shot I put the short lens on the body and take a dynamic pixel shift shot. I don't have to carry a ball head and change the tripod setup to take a landscape shot. I did that and found I didn't take the shots. It has widened shooting opportunities for me in practice, with quite good results.
The autofocus improvements were worth every penny. The other things are an unexpected bonus.

I disagree with the last comment. Put a 150-450 on it and shoot moving targets. The difference is substantial.
I'm getting a stop better noise performance with the Mark II.
The dynamic pixel shift is very handy. Again in low light conditions you can get a clean shot which otherwise would require tripod and long exposure.
The K1 is a remarkably capable body. Some people aren't going to be pushing the limits of it's capabilities, and an upgrade wouldn't give them anything they need. But there are real improvements.

I have the DFA 150-450, and it is remarkably better. I'm finding to my chagrin that my poor results can't be blamed on the camera body anymore. I don't have any of the newer shorter zooms or primes. The 43 Limited is fine, it focuses reliably.
The Dynamic pixel shift is also useful. I've been using it in low light conditions to get a cleaner high iso low noise shot. If you have a tripod the Pixel Shift works quite well, and the time to process for the dynamic mode is a bit of a nuisance, but it is one of these features that I use because it is available and works handheld. I'm moving into low light conditions in the fall and winter and suspect I will use it often.
On the K1 I had set the iso limit from 100-6400. The Mark II is 100-12800, and I'm going to notch it up a couple stops. I'm getting remarkably clean shots at 12800 in some conditions, and I use the high limit as an indicator rather than an operating limit.
This is 1/250, f6.3 iso 12800. Very minor and easy noise cleanup on the background, a bit of chroma noise. This was dynamic pixel shift.
