Canon is so stupidly shortsighted!
[X] No, I will not throw away my 580EX II and 430EX/IIs!
[X] No, I will not buy a single 600EX-RT or ST-E3-RT until such RT-receivers are available.
If they wait any longer, Canon will get burnt by the Chinese rip-off manufacturers who are undoubtedly already reverse-engineering the RT-protocol and will bring out those damn RT-receivers and RT-master units any time soon.
[X] Yes, if they deliver the goods before Canon does, I will happily buy a Yongnuo or Phottix ["Odin RT"] master controller unit plus matching RT-receivers.
