Well, without Adam's full review, I couldn't really say. If I were to hazard a guess, I would think that the advantages are the WR, the silent focus motor, the
possibility that it is optimized for distant objects or celestial objects (as a telescope design?), and the weight.
Disadvantages so far appear to be IQ on a chart, minimum focus distance, prime vs a zoom except this time zoom is kinda useful, etc. The FA*250-600 has been praised by users to be sharper than the Sigma 500 F4.5, so that might give us an idea of how the DA560 fares against that lens.
As for price, I actually don't even know the original price of the FA*250-600. I do know that I sorta lust for it though.
