Version 3 is based on the brand new AirNav FlightWatch software with MANY MANY more features. FlightWatch will be released in Oct 2009 (programming goes on, especially on our flight data servers in Dallas and Boston).
V3 only after that (a few months later). AirNav FlightWatch will be the only flight tracking application showing data from several different sources: RadarBox, RadarBox Network, FAA Radar System, ACARS, Flight Plans, Manual Input. It is being developed for our airline/airport customers but I'm sure we will work out how to have a non-professional version available.
