With Sonos planed obsolescence with older models (the upgrade your old play 5s for 30% discount on newer models - despite some products sold upto 2015 thing i read today - some 'legacy' products will stop working may 2020)
When can i expect Sonos playbase / sub / play 1s (in 5.1 set up) to also stop being supported and require newer models? 2025? i would likely like to sell while they have some resale value to them.
