Well, at $12,000 a copy for something in the footprint of a PVS14 it's going to be a long damned time. It took a long time to afford NVD's for our soldiers, and just about as long for our brass to understand how critical these are in modern battle. Remember that current NVD's are strapped to a soldier's ass/thigh while he jumps in and out of foxholes all day long and wipes lenses clean after a sandstorm-for as durable as they are, they are still electrooptical devices...
I suspect they will be phased in like NVD's are. High-Speed outfits get them first, then they will be handed down to regular joes (like 1 per squad), then handed down to the guard once the full timers have what they need. A lot of people don't know it, but there are Guard Units still using the PVS5 dual-tube goggle...
It's probably fair to say that the new top of the line NVD's we buy as civvies are better than 90% of what the military has accumulated in the last 15 years.
Personally, if I could get a PVS14 in a thermal configuration for say, $5,000 I'd do it and sleep real well that night.
