"Revox is/has building/built a new R2R in 2017..."This is puzzling, but not that much. If such thing had actually been produced, ReVox somehow forgot to mention it on their website. Not in the news from 2016 or 2017, not in the history of their tape machines.
Internet has many pictures of 2017 ReVox tape recorder. All of them on some enthusiast websites or YouTube channels. Nothing solid, though. No review of a machine that would be expected to be eagerly awaited. No real pictures. Nothing.
Well, something...

Sad news, ReVox has not been producing tape decks for many years now. Not in 2017. It has not contributed to this revival yet.
