There’s a fair bit of discussion of what RoonOS 2.0 will bring when launched. Danny (CEO of Roon) has engaged on the topic, and there has been some back and forth on whether RoonOS 2.0 will support UEFI boot, which is the key dependency needed for NUC11’s. I’d have a hard time imagining it won’t be included, given that ROCK is a key offering and NUC10’s are increasingly in short supply.
So that’s one person’s guess that they (NUC11’s) will be supported this year, but I don’t work for Roon and they (correctly in my mind) don’t often make firm commitments.
