I didn't see any other threads discussing the transmitter, other than one on the 560 III. Looks like Yongnuo released the new transmitter back in June. Looks promising, remote power and zoom control of the 560 III, plus dummy triggers for 602 and 603/II receivers.

There's a couple of reviews online. Anybody get one of these yet?
