If I had a d7000 I probably wouldn't upgrade but for me there seemed little point buying the older camera, I prefer the extra af points, better lcd, the slightly better menu, the 1.3 crop will be a great option for me personally and 24mp over 16 is pretty substantial. Plus by all tests I've seen better IQ if only slightly. Info button useful to.
infact I always hated nikons menu but they must have changed things, this one I find easy to navigate.
