I'm amused this is what it takes for me to stop lurking in the shadows...
But I don't think that's a fake.
The text string "Interactive Preview" exists in version 2.1 of Studio. I can't find any way of accessing it, but it's in there.
Also, if it's fake, it's *perfectly* done, down to having an offline Juan chat window and Victor as one of the tiny handful of Youtube channel friends (with Victor's only video being a demonstration of RealFlow used at the Goya awards).
I think this is legit, and that makes me very, very happy.
