Wow, not only is Yongnuo coming out with the remote groups controller, but so is Cactus:
CACTUS – Remote Manual Radio Flash & NEW V6 Transceivers Coming | FLASH HAVOC
and the Cactus v6 is compatible with the Cactus v5 which probably several of us have.
I think one of the biggest advantages of this approach, besides the remote control of power - which would be great, is that each enabled 560 III would eliminate the 2 AAA batteries associated with that separate receiver. I assume the receiver built into the flash unit would also be powered by flash's AA's - and they seem to last a long time for me.
Are folks out there happy with the YN-602, 603's as far as workmanship and design?? It looks to me like the YN's also have a smaller case width wise.

A story about Nikon SB-900 flash. The ex-pres. of our photo club, decided she was going photo professional. And she is doing a good job at it - the usual portraits, weddings, etc. She told that she was in a hurry one day and set her 900 flash on the seat of her car instead of packing it up. She made a sudden stop, the flash slid to the floor and died. $500 down the drain, so to speak.
I've tried to use flashes in "fine art" photos on a few occasions. I've lost 2 yongnuo flashes doing that. In one case, a flash slipped out of hand and hit the concrete sidewalk. DOA. In a second case, I apparently forgot to pick it up after using it at Fort Worden on Artillery Hill. When i went back to get it the next day - gone. These both were the yn460 IIs. But replacing a $45 flash is a lot cheaper than replacing a $500 flash, if i've done the math right.
One thing i love about the K3 - the onboard flash allows one to control the output down to 1/128th manual power. If you wanted just a "kiss" of light for the face of that cat or dog or ???, its perfect. It works great for that. IN the past, you could adjust the onboard flash down by total of 2 flash ev's but it still way over powered most applications that i wanted to use it for.
