It's good you have samples already, trouble is that you will get the board finished and tested, then just sit there for months waiting on a real supply of chips. I guess you can mine on the prototype in the meantime to help pay overheads.
I, for one, am grateful there are people putting time and money into this design, thanks Terrahash! A lot of us are depending on this design, a board re-roll will easily eat a week or two, the earlier the better!
