As for Pentax, I believe their strategy should allow them to expand their product line with OEM products, rather than rebadges (as a birder, why would you get a Pentax with a weaker AF, and the same lens you can buy cheaper for Canon/Nikon?).
Even "killing" the 150-450 might be a mistake, while you'd love the added reach of a x-600mm lens, others might prefer the more manageable and shorter lens.
Last but not least, the DA 560mm f/5.6 is much more affordable than a 600mm f/4 from the other manufacturers.
Obviously the D500 + a great lens like the 200-500 or the Sigma sport or the T G2 are second only to expensive FF lenses, even then not by much.
"Who would get a Pentax for birding?" A pentaxian of course!
Lastly but "least" the strange DA 560mm is now cheaper than before, I've just looked, Idealo have it at 5499 euros, yes it's cheaper than a Canikon 600mm F4 .........
........but we all know what an extra stop of light costs at 600mm and the fact that it's sharp at that aperture, where the DA struggles at F5.6.
