More important information coming up for this new wireless technology:

Some important notes from above link:
1. Flash sync speed: When used for radio-based Wireless E-TTL with any Canon EOS camera introduced prior to the EOS 5D Mark III or EOS-1D X, the maximum available sync speed for flash will be one stop slower than normal. (EOS 5D Mark II or original EOS 5D – 1/100th second; EOS 7D, 60D, 50D, etc – 1/125th second; all previous EOS Rebel models – 1/100th second.)
2. No high-speed sync: For radio-based wireless E-TTL, the only cameras that allow hi-speed flash sync will be the EOS 5D Mark III and EOS-1D X (as of March, 2012). It's not possible with any other previous EOS camera bodies, when combined with the radio-based wireless flash system.
