CONCLUSION.......
Well the Nikon and associated lenses and flash went up on ebay.
Autofocus - AF-C worked plenty good, and in fact worked inside in pretty dim light (light was dim enough that my settings were around ~ f4 ~1/90 and 3200 iso), but of course most suffered from motion blur at this speed. The Nikon IS faster and better, but not by any wide margin. I really do not think it would affect most people. You what will affect most people? The small buffer on the D7000. The buffer fills and you are stuck there pressing the shutter release until it can snap another pic. Indoor low light single focus slight edge to D7000, but has yet to be a problem with 3 nights of shooting a 2 and 4 yo in dim conditions. MY EARLIER POST ABOUT BAD INDOOR SHOTS WERE DUE TO A SIGMA LENS PROBLEM>
High ISO - Same sensor, but I give the edge to the K5. Never in the 8 months of having the d7000 have I ever been wow look at what I pulled out of this. Why I do not know, but the K5 just look and handle better.
Handling - Green button!!!! why have others not implemented it? Am I the only one that loves it the way I do? The K5 is a little small for me but I will get used to it again.
Flash - People always rave about CLS. And I do not understand why. I do use alot of flash and multiple flashes, but maybe I never truly understood CLS. To me it was multiple wireless flashes that could be independently controlled and triggered by the on board flash. You still blew bounced pictures, or sometimes underexposed. You still had to adjust the flash output most of the time. I really do not see a difference in it and Pentax's system except the name. When I had the 7d it was the same as well. The flash sync speed does not effect me, as when I want bright daylight fill flash I am most likely lens to nose with a snake and HSS works great.
Finally I just have always liked Pentax. I bought my k10d the night I found out my wife was pregnant with my first child. Now time for lens shopping!! Anybody know where to get a sigma 100-300 f4?
This is all motion blur but I laughed at the face
