They have stopped manufacturing the Skyview Classic, and they have stopped developing new software except for minor improvement and bug fixes. The HDX is their focus. One of the wonderful things about the Dynon philosophy, is they developed the Skyview to be an easy upgrade from the D10/100/120/180 system, and made the HDX to be an even easier upgrade from the Skyview Classic system. Even the holes cut in the panel don't require a change from the Classic to the HDX, and all of the remote modules and wiring are identical. The D10A series was a home run in its day. The Skyview Classic and then touch were a home run in their day. The HDX is a home run today. Now, the addition of an IFR GPS, one of the most widespread desire and one of the most narrow list of options, I believe is a home run.
