16LPILOT,
When I left the King Booth I was shaking my head. After thinking about it for a while I decided that since in the next decade or so we are going to replacing most of our avionics equipment to be able to work with ATC's next generation IFR system, King sees a big market developing. We are going to need WAAS then ADS-B that talks to the WAAS GPS and then an MFD to data link to ATC. I think King decided that the 770 would not compete well with the 530. The 770 does not offer enough to draw customers from the Garmin. The way back into the market is through all the folks who have 2" high GPSs (89,90,94). The small GPS does not have much space for a screen but it is adequate. If you want to add glass they have an 840 for you. King is probably thinking that lots of King GPS owners might like a WAAS GPS with minimum installation hassle. Why have they not done this already? I think they were hoping for the 770 but found it had no market. They GPS specs for ADS-B just came out so it will take a little time finalize the design and get it tested. The biggest motivation for wanting to keeping their GPS market share is to sell databases. I bet they make a ton on that monthly annuity. I should hasten to add that this is total speculation on my part. King has never asked me my opinion about their marketing strategy.
