I have been playing a lot with off-camera flash using a 580EX and a pair of 430EX Speedlites. I have been triggering them with four Cactus V5s, which are nice, simple radios, but no E-TTL, but maybe the most annoying feature is that you have to climb ladders to adjust settings manually or wake them up when they go to sleep. [
I would love to perhaps upgrade my wireless flashes, was considering taking the plunge into Pocket Wizard land, but could also go the way of a 600EX-RT and the ST-E3-RT trigger. I love my 430EX flashes and I am wondering whether Canon can be expected to come out with a 430EX II replacement with RT any time soon.
I have scanned the Lighting section of the forum, have not seen any good rumors or gossip, so I thought I would throw out the question for those who may know or have an informed guess.
