It is more than obvious, that XBTec have not got anything to show yet. Even if they ship "something", they will have to pull that out of their arses. No chance they have a working unit now, otherwise they would at least post some video.
So, if they do not have the production of their miners in some kind of a parallel reality, there are ZERO chances, that they can keep their promises.
I want to see, what jimmothy has to say about this.
P.S. Popcorn time
