Is this a thread about you or about photographers in general? Because if it is a thread about whether or not full frame would give you benefit in your photography, that is a question that only you can answer and it is perfectly fine to answer "No, for my style of photography it won't make a significant difference." But it is futile then for other posters to produce images that would be hard to produce on crop sensors and have you say "Well, I wouldn't shoot that kind of thing anyway."
I think for portraiture and low light work, the K-1 will show significant improvement over current APS-C cameras. For macro shots, I think you would be hard pressed to see a difference. Wildlife is sort of a toss up. You will see a difference if (a) you can get closer or (b) you can afford a longer lens. If like me, you are stuck shooting a 200mm f2.8 or a consumer 55-300 APS-C zoom, you probably won't see much difference at all. From a landscape standpoint, this is a dream camera, with tons of a resolution and the addition of pixel-shift which can give images a medium format level of detail/dynamic range. I don't do astro photography, but it seems as though that would be a no brainer as well, as it seems as though those folks are always trying to get faster lenses and the addition of the astro tracer could help out some too.
You do a lot of street photography, kh, and I have no idea if you would see a difference in your photos. If you are satisfied with what you have, then why even ask the question?
At the same time, I think the answer is clear -- for certain types of photography, the K-1 is definitely worth it and there is no particular reason to hold back from getting one if you want it, even if it doesn't actually make your images any better.
