Different people different needs, and I has my own point.
I comes from minolta user, and switch to Canon after I lost my gear during a trip (and that time, minolta gears suddenly dissapear from market or the price sky rocketing since take over by sony).
My Sony gear is mainly used for walkaround purpose.
My Canon gear is mainly used for potrait and candid. And for this potrait and candid, I need to create 'greater effect' by maximize using of different AF points (it's all about composition).
I seldom PP, the most is change WB, change contrast/sharpness a bit, and sure sometimes cropping. Never touch PS.
I can see 39 AF points is arguable here, but it's a potential for me to make my composition better.
I'm not loyal to a brand, I only care which brand offer tech (or thing) that can help me better.
Alright sure you look for tech or brands that help you better, then why d7000? According to speculation, not sure how accurate, the d7000 is priced around 1800 to 1900. If it turns out to be true, it's only 200-300 shy of the 7D. And by changing to Nikon from Canon, you are essentially losing money from sales of your lenses. And have to spend time scouring for the appropriate Nikon lenses. If you budget allows then go for it then.
Sometimes being loyal to a brand isn't by choice. There are actually quite a number of Canon fanboys wanting to switch to the D7000 just for the specs and price alone, but most chose otherwise because of their current collection of Canon glass.
Something for you to think about.
