A new Speedlite or two
We're told Canon could be announcing two new Speedlites in the first or early second quarter of 2013. Both of the suggested Speedlites could be to replace the current Speedlite 430 EX II. The guide number of the new flashes would be 45. One of them would be compatible with the ST-E3-RT radio transmitter and the other would be a standalone unit without radio capabilities. No mention of whether either would have the af assist light/video light like is found on the EX 320.
There would be no new features to the flash functionality that aren't found on the Speedlite 600EX-RT. When questioned about the possibility of a Speedlite 600EX without the “RT”, I was told that it was possible, but not in the immediate plans.
