They don't sell the numbers like Canon and Sony so they would have to spread the cost out over a smaller unit number increasing cost of the bodies up to Sony Canon level so they lose their value price point. Then if they did improve the tracking they don't have the greatest lens selection for sports and fast moving wildlife so if the body is the same price level you will go with the brand with the better lens selection. These are just my opinions but I think that is why Pentax doesn't Improve the tracking auto focus ability. They are sticking with landscape, portrait, product photography and the lenses they have released for the K1 show that.
I complained about the tracking and speed of auto focus of my K1 and DA560 so I switched to Canon. The lens I bought was older than the DA560 and the body I bought was older than the K1 and they out perform the newer Pentax designs in autofocusing. Until I used them back to back I never really knew how behind Pentax was in that department, I read the threads before but had never used a Canon so I couldn't really relate to the performance.
The K-1 is more in the 6D price range and probably has similar specified auto focus. I thought you were shooting with a 5Dsr which, while 9 months older, is in a different price range entirely.
But certainly if you are a hardcore wildlife shooter, I would consider Canon and Nikon long before Pentax -- as much due to the presence of really long lenses in their line up.
