Pocketwizard Firmware Beta available for 1DX, 6D and 70D

I was happy to see that Pocketwizard has finally released a firmware update (Beta) to make the Pocketwizard MiniTT1 and FlexTT5 for Canon fully compatible with my 1DX (as well as the 6D and 70D). (see www.pocketwizard.com left side of the page). I'm planning to download the firmware updates and give them a try later this week.

In the meantime, I am wondering if anyone has already downloaded and tested the firmware update with the 1DX?
If so:
1. Do you get full compatibility with the AC3 controller as well?
2. What's the fastest Hypersync shutter speed you have been able to obtain?
3. Any problems identified?

I look forward to hearing from the community and to trying it out myself.
