I run the partner programs here at Roon Labs.
We are currently working with the Sound United team to add the HEOS line to the Roon Tested family of products.
If you zoom-in, you will see that is a Roon Tested logo in the Youtube video. That means this would be an Airplay and/or USB integration, depending on the device.
Note that this is not yet announced on our end, so they’ve let the cat out of the bag. If you were to hook up one of these devices this moment, you wouldn’t get the full RT treatment, but it’ll come soon.
We can’t speak for any partner in regards to future development or timelines, so you will need to ask them about any Roon Ready plans.
