Will the be avaible soon?, any can tell.
Becouse i am waiting for them before i buy this amazing drone

Will they even be available at all?  

You could be waiting for a very, very long time.

Given that the Air also uses FOC ESC's like the MPP you would think that low-noise props are coming but that said, they never happened on the Spark so your guess is as good as mine! Next month? Never?

Would be really nice - but i doubt (sadly) that DJI will do it. but anyway give waypoints 1st!
Maybe it emerge on market as a 3rd party product...
