The 100% crops of birds shots look good to very good.

My Sigma 500/4.5 is softer wide open. However, I don't even care about it. To obtain decent DOF, especially for medium to large BIF shots, I shoot mostly at f/6.3-f/8. The recommended f/8-f/11 of 560/5.6 is slower, indeed. There might be an issue with isolating the subject.

Fast and accurate focus is a plus

It may be balanced well enough. However, while I'm comfortable with hand holding of much shorter Sigma 500/4.5, I'm not sure about 560/5.6 when extrapolating my Sigma holding experience. And I am 6'2" tall. I trust MightyMike that the lens is OK for holding, but my technique might be deferent.

All in all the good new is the lens has been developed and released. So far, I don't see very convincing reasons why the 560/5.6 have to be chosen over cheaper, but excellent Sigma 500/4.5, however.
