To cut it short, and relay things from OG: he mentioned he hadn't seen all of the audio files. He specifically said he was waiting to look at the Windows Edition tomorrow to double-check things, but people have continually messaged him about certain things.
I know he found a full-blown tutorial, among other things. I didn't bother to translate the names for certain things because as I told OG, it'll probably be changed during localization and is a waste of time to do it now.
So if it's there, if it's a placeholder for something to come, or to not be a thing in general: no one can really say currently. If OG says it seems incomplete to him, I've enough faith to listen to him about reading it properly at this point.
