No its still in development in Shenzen, though I don't think it will be too long before it goes out for wider testing.
Here is a snip from Ecowitt.net for one of the test units to wet your appetites

As I mentioned before I promise I will share what I can when possible or Lucy will.
As for the WS80, its been great. We have seen some cold temperatures down to -5C but no issues or drops so far in performance.
The production version will be sold with a heated plate embedded which folks can connect up via long extension cables to power the heater. They are also looking at developing other alternatives for powering the heater plate. So in theory the ultrasonic anemometer will be suitable for all climates. My test unit has the heater embedded in the design but no cable and its not possible to retrofit so I have been watching the performance closely.
I meant to add that you can have both traditional anemometer and the ultra-sonic if you want, but you must choose on the console settings or GW1000 which array you want to take data from and upload etc
I have 1 Console and 2 GW1000 so I have the capability to mix and match what I want to monitor.
