D300s is about as 'pro body' as I've had the desire (aka, funds) to go.
Have you ever owned a D7000? Your opinion may change once this is rectified.
Honestly, I'd love a D3 series... but for what I do the D7000 is more camera than I'll probably ever need, and I'm glad (and lucky) to have one. Full frame is of no interest to me, most of what I shoot is wildlife and the D7000 handles that even better than my D300s did, including birds in flight.
So tell me, why would I (or others) want to spend a minimum of $1500 more for a 'pro' body when the D7000 is fully capable for all of my needs, only to lose some features that I've come to enjoy?
