We are definitely planning to support Rhino 6 and are quite far into the development of that already and have the basics under the hood going but we still need to do quite a bit of work on the UI before we can release any kind of version of it. You have probably seen the announcement regarding the change over in developers to us at migenius and we definitely want to talk more to users once we have the new dedicated forum running on the Iray plugin site. Users can reach out to me personally through our website at http://www.migenius.com/contact, just mention it's regarding Rhino. I monitor all emails that come through that page.
