@Beophile: you are more or less spot on. The following products are updates as pr now: A6, A9 2nd gen, M5, BS1+2 and the Core.
A software update for the BeoSound Essence 2nd gen. and BeoSound 35 will follow in the next couple of weeks.
A free trial offer for Deezer HiFi will be offered by B&O when the last two products have joined.
