From CNBC:


“Sonos said people who own the older products can keep using the older speaker in their system, but the new speakers won't receive updates either. A spokesperson told CNBC this is because all speakers on run on the same software, so an older one will lag the system behind if it's still in use.


Sonos told CNBC in May it will launch a way for customers to segment the older products into a separate speaker group, which won't receive updates, while another group of newer products will continue to get new software.”

My Android phone no longer is fully compatible as of 6 months ago. So while most companies work on improvements as Sonos should so they could be more compatible with HiRes, they have been working on obsolescence!

I think I have figured out the acronym for Sonos

So
Old
Now
Outdated
Sucker
What will happen is as soon as your music service makes a change and Sonos changes their software to stay in sync your done.  You can proly keep them around for streaming radio.
So will the original Play:1 still receive updates? I’ve only heard about the original Play:5.  
They are sending out emails.  If you have unit that meets the critirea you should get an email.  Even if the product is not registered as they see it on your system.
