Can anyone from Canon offer an opinion or reason as to why the 1Dx does not have the capability to communicate wirelessly with the 430EXII? It seems strange that my 2 year old 7D can do it but yet the 1Dx cannot. Was this to force customers with this flash towards the 600EX-RT? I'm guessing that this has been a deliberate action by Canon, i.e. to make them incompatible for wireless communication. When I tried to hook them up I was baffled that the settings would not register the flash, turn on the 7D and there it is.
Strange decision Canon but an explanation would be appreciated.

Maybe I'm missing something, but the 7D uses its built-in flash to wirelessly act as a master flash to any compatible Speedlites, while the 1Dx doesn't have a built-in flash to do this regardless of Speedlite.

JFO, you are correct, my error, I'd forgotten you need to have the pop up enabled.

Ah, gotcha. I was a bit baffled, because for some of Nikon's pro bodies, I think they still have a pop-up flash, and I wasn't quite sure if that was the same for the 1D series since I haven't worked with them firsthand.
If I remember correctly, the 7D and T3i's pop-up flashes can do wireless control, so I'd assume the T4i does also. Not sure about the 60D, though. For the "pros", I think Canon is pushing for their new ST-E3-RT transmitter and 600EX-RT's -- great for someone with the $$ starting out or to sell their existing gear to upgrade, but I don't think Pocket Wizard / RadioPopper, etc are going out of business anytime soon.

Currently the T3i (600D), T4i (650D), EOS 60D and EOS 7D all can use their pop-up flash to contol other speedlites using the pulsed light communication.
There are some differences though.
T3i / T4i / 60D - control at most 2 groups of flash, Speedlite groups A and B
7D - control 3 groups of flashes Speedlite groups A, B & C.
None of the built-in flashes can force the slaves to high speed sync mode.
To be honest I think Canon missed a trick by not building an ST-E3-RT type transmitter inside the EOS-1D X, though maybe getting radio signals through the metal body was the issue.
