Who knows if it’s still coming, but I know that it never launched. People seem to be happy with the standard Dream Wall, but I have to wonder if it wasn’t quite popular enough for them to decide to launch the Pro version. Then again, Ubiquiti is pretty notorious for abandoning things after announcing or EAing them.
You could always grab one and then sell it if/when the pro is ever released. It’ll be interesting to see if products get launched any faster after announcing now that the EA Hardware program is gone, but in the past it would take a while for things to go GA. Better is the hardware that exists and can be bought today than the hardware that’s been announced with no known release date.
