Pricing ?????
Since the AR 5700D will have a significanty higher spec than the new Icom, my prediction is at least £3000 plus.
Multiply that by 3, or more, for the 'Flagship' reveiver. Both are desktop models, and I see they are still showing the AR-DV1 at the Fair, which is small enough to double as a portable receiver too of course.
The AR-DV10 handheld is anyone's guess, but it will have Whistler worried no doubt, however I imagine it will be quite a lot more expensive.
The basic firmware of the new models is likely to be the same or similar to the AR-DV1. That may be good for AR-DV1 future upgrades.
