AcroSport, sorry I shouldn't have buried the link in the text.
My reading on the overall situation is:
I don't think that the new model will ever eventuate, the economics just don't work out. Why would you develop a radio for such a small market? There are what, 30,000 pilots in Australia? Even if half of them fork out for a radio that's only 15,000 units. If they are replaced every 10 years that's only 1500 units per year. If the development cost is $500,000 (a low guess number) and you want to recover over 3 years you need over $100 per radio before you have even built, marketed or shipped anything? This assumes that you get the whole market so the reality is that this is an even higher number.
