The 5D2 is my go to body when I have a bit more time to set up the shot. 61 point AF really doesn't do jack for me there. About the only real potential attraction is in the additional dynamic range. I do a far bit of nightscape/starscape shooting and the III may really be a big improvement on the 5D2 there. That's a pretty thin argument for a $1500 (at least) upgrade, though.
I know that every time a new body comes out all the old guard try to justify their now obsolete cameras with the "it still takes great pictures, who needs the new toy" mantra. But in this case I don't really see the 5D3 offering me a whole lot I don't already have.
I too own the 5D2/7D combo. When I go into the woods for wildlife and birds, the 7D has my 500mm lens, but the 5D2 is around my neck with the 70-200mm mounted and the 24-105mm in a vest pocked. Before the announcement, anticipating pixel density similar or finer than the 7D, I was thinking of moving to the 5D3 as a wildlife body. However, apparently Canon is positioning the 5D3 to be a superior video camera, where a coarser pixel pitch makes lots of sense.
Despite that fail, I'll be buying a MkIII in a few months because the high-ISO performance and much better AF function will make it superior as a second camera for wildlife. Now, when I switch off between the 7D and 5D2, the AF slow down and refusal to shoot can be infuriating. Hopefully the MkIII will solve that.
The price rise is annoying, but I'm actually surprised that prices on the old models held low, despite the yen/dollar exchange rate working against the dollar through the whole production period of the MkII and the 7D.
I AM looking forward to the 7D MkII now, with the new Digic-5 processor the high-ISO performance should be much improved, which will pretty well address my only complaint about the 7D as a wildlife shooter.
