No, I confidently predict the FT991 will sell for less than £1000 before the year is ended. If you are in the market for a 100W radio it is a toss-up between the IC7300 (SDR based) and the FT991. At the moment, the IC7300 looks better value.
Yaesu may announce a (long awaited) FT817 replacement at Dayton next spring but don't expect to see units in Europe before autumn 2016 or later, is my bet. The Yen exchange rate has vastly improved (making Japanese goods less expensive to buy) and now the FT991 has a serious rival - result is Yaesu has to drop its price for the FT991 or they lose out. My advise is wait a few months.
