Yeah, I am really curious about this too. Recently Octane released a plugin for Daz too. But still no news for ProRender plugin for Daz. As far as I saw from other Daz related topics, AMD answer always is "Its iray and cuda" or "use Blender Bridge". I mean, most of us aware these things.
I wish AMD share some info about this. "Like we are working for it" or "yeah, this is also one of our future plan but no ETA" something like that. Seeing same basic answer in every topic is kind of bothersome.
