Re: WS-1400-IP Out of Stock - New Upgrade / Model Version Coming?

New Firmware for the Observer IP is out ... v4.1.4 ... from the site revision history:

"Now supports WS-1600-IP weather station."
http://www.ambientweather.com/wswsfiup.html

I cannot find a WS-1600-IP.  Is this an older model?  Or is this something New from AW?
