Picked up a new 7100 over the weekend. Yes, that means another picture of a dog.
Initial thoughts: it's quite the refined 7000. Very informal tests show that I lose shadow detail before I do so with the 7000. I suspect the gain in AF performance will be worth it for strongman / lifting events. I'm glad I still have a 7000; I would have to think long and hard about being able to live with the 7100 as my only body.
