Lucky for you all, I speak fluent Japanese. I've taken the trouble to translate the conversation in the first video:
Interviewer: Now, sir, now this is a beautiful camera, but can you tell me if the rumors are true?
Cosina representative: Yes, the rumors are entirely true. We have no intention of ever manufacturing or marketing a camera like this. Don't you know? Film is dead!
Interviewer: But why make such a detailed prototype? I can even open the door and extend the lens.
C.R.: This prototype, as you call it, is just wood and styrofoam model painted black. My nephew put it together for a project at school concerning obsolete technology. I saw it and thought, hey, let's bring it to Photokina and drive those Rangefinder Forum kooks absolutely crazy!
Interviewer: That's brilliant! What a fun idea. Did they fall for it?
C.R.: Are you kidding? They lit up the board for weeks talking about nothing else! They argued about the lens, about the film plane, about the price. My colleagues and I would log in every day to read what was written and sh&t ourselves laughing.
Interviewer: It's amazing that a little bit of wood and styrofoam would cause such a ruckus.
C.R.: I know. But I tell you, they are absolutely crazy on Rangefinder Forum.
Inteviewer: Do you have plans for more humorous antics?
C.R.: Now I am going to circulate a rumor, from a very high source, that Kodak's Tri-X film will be discontinued in 35mm and 120 and from now on will be available only in Advantix and 110 formats.
Interviewer: What fun that will be. Thank you so much for talking to me.
C.R.: It was my pleasure.
