According to dealers there is a new soundbar in the pipeline, as launch date they expect spring 2019. They claim to have seen pictures already. From my side I hope they do the soundbar right with HDMI eARC and the possibility to connect other B&O speakers via WISA.
Also there will be a 77 inch Eclipse, but only sometime in 2019 .... And if they make it too expensive, you have then the option to buy the LG 77 C8 at 5000.- euro (lowest price in Germany today) and you add just the new B&O soundbar ....
No refreshes for the Beolab 17,18,19 neither (they are on the market since 5 years without change)...
