These small market products seem in general to take a lot longer than they're reported to. I know from following their Twitter feed that it is "close". But that said no timeframe. It was suggested in another forum that projects like this in general are not attractive to the companies that manufacture components because the volume of components is initially a lot lower than the larger electronics etc. companies they're dealing with. Apparently if this is correct information it causes such projects to be "back burnered" by the big guys in favor of other big guys.
Case and point, I waited nearly 6 months to get Nuand's XB-200 HF/VHF transverter for my bladeRF. It seems to have been worth the wait though as preliminary performance seems excellent. Many people have been waiting for the HackRF for over a year. It is close to shipping finally. I have one on order as well and I've only been waiting since late June. I'll order an Airspy as well as it will serve well as a portable SDR whereas the other two are better suited to stay home, especially the BladeRF which still does not have a proper case to house both the main board and the transverter.
