Canon ST-E3-RT & autofocus assist beam

Background: I'm shooting a Canon 5d3 with firmware 1.2.3. I'm getting in two 600ex-rt flashes and the new Canon ST-E3-RT transmitter.

I'm reading conflicting reports that the Canon ST-E3-RT does not provide an autofocus assist beam the way the older optical Canon ST-E2 transmitter do.

Is this TRUE?

Sidenote: Anyone have any suggestions for tutorials/books to get me up to speed on the 600ex-rt flashes?

Thank you - Dale
