Seriously, the price will probably stay the same, as this device is now over 5 years old and Sonos actually guarantees 5 years of updates for all devices. Maybe a new speaker will come soon, who knows. On Toppteise.ch you can see that the 495.- is not really a reference either.

As long as Digitec is funny
The SUB2 became a whopping 100 Sfr. more expensive from December 19 to January 20 and it wasn't even on sale.
