I'd also like to point out that there isn't a 35mm f1.2 lens available for the K amount at any size, weight, or price. Yes, these are the "cheapie" lenses, but at least they actually exist for mirrorless cameras. Some of these have no DLSR equivalent.
Don't get me wrong, I LOVE DSLRs. I have a Canon SL1, 10D and D30, a Nikon D70, A Pentax K10d and a (an?) *ist D, an Olympus E-1, and I'm sure one or two more I can't remember right now. In most situations my SL1 is my go-to camera. I'm hoping Santa brings me an original 5D! I also have a Sony NEX-3, a Panasonic G2, and have had a half dozen other Sony mirrorless models and a couple Fuji X cameras along the way. There are many on this forum (not you) that always comment on mirrorless cameras, whom I'm pretty sure have never really used one. Many of those that have only ever used them with adapted K mount lenses. Of course the size advantage is partly lost doing that! I do say partly however - any full frame DSLR absolutely dwarfs a Sony A7, A9, et cetera.
Yes, a K1 is certainly larger than a Mirrorless full frame body. However, in the grand scheme of things, it's not THAT much larger that it makes a difference. A Sony body will take up just a somewhat smaller (in real terms) space in your bag than a K1.
Prior to getting my K1 recently, I was a dedicated Sony user (I have an A7iii and an A7riii), and what I will say is that those who say mirrorless is a toy are kidding themselves, and those who say that the dslr is dead isn't quite correct. There's some advantages to both (although mirrorless is certainly closing the gap). Quite frankly, Pentax could change nothing about the K1, and just add an EVF and I would be thrilled. If there's one thing I miss having on the K1, it's an EVF (even the lesser quality one on the a7iii).
Re: your comment on the lenses: This is spot on. If there's one thing that I am extremely hesitant on with Pentax is the lens selection and future roadmap. Yes, vintage lenses are great and having an ungodly number of years worth of them is fantastic. But it's also great to have new and better stuff coming out, especially stuff that is niche, that make this platform alive and not dead. With Sony, I literally have access to anything. I have all the Sony first party lenses available, I can use any vintage lens I want, AND I have 3rd part support from companies like Tamron, Sigma, Voigtlander etc. With Pentax, they've basically lost all major 3rd party support, and Ricoh seems to feel that there is no urgency in either having a wide variety of modern lenses, or putting out products that make people want to join the system. This is one of the reasons why I originally left the brand in the first place last year. As much as I have loved the K1 for landscape purposes, there's enough inherent issues that make me nervous about staying here. Granted, the fact that I have my Sony gear and *most* of the lenses I have for Pentax (which aren't many mind you, and mostly vintage)will adapt if I ever left the K1 again helps me stay here.
Really, as much as Ricoh/Pentax say they won't, they *need* to go mirrorless, and they need to do it well. It's the only way to stay alive. And there's really no excuse for them not to (other than their hugely limited resources). Canon and Nikon have both shown how to move over to this world. Make a good mirrorless body, make a good autofocus adapter to the K mount, and people will stay with the company, but also have room to grow in the future. Just make sure the flange distance this time makes the body a universal receiver, rather than a universal donor.
