BMPCC4K with ATEM Pro HD?

I've seen the update allowing the use of the BMPCC4K with the ATEM Mini series, has anyone heard about an update for the full size ATEM switchers to allow this control?

Not available at this time, as the larger ATEM HD CCU control is only on the return SDI feed to thenBroadcast/Ursa Mini cameras. The HDMI CCU Control on the ATEM Mini is over HDMI to allow,using the Pocket cameras for live streaming.

Yeah Denny, I'm aware of the difference in sending CCU controls, but was wondering if BMD might make an update to these switchers to include CCU on the HDMI ports.

I'm also not sure if there are some hardware limitations that make this impossible to do. Mostly just curious!

Thanks, my guess it is a hardware limitation on the older switchers, perhaps new ones might be able to have both running together, with separate CCU screens for the control software.
Cheers
