Sonos never announces those types of things, and anybody who knows aren’t saying.  The closest we get to knowing what is coming is when they file at the FCC, and that only happens a few months before release.  

Was thinkin of buyin a pair of Five with a sub, was just hopin am not too late as Fibe may be upgraded with Dolby Atmos

Five

I have a pair of Fives bonded to the Sub Gen 3. Very happy with it and honestly, would not care about Atmos as I often use the Fives with my turntable and CD player anyway 

The Fives are fantastic speakers!

Thank you very much, will buy them

Sonos has just released the Era 300 with Atmos. Why would they also ad it to the Five?

Yes, actually
