I wouldn’t think so. They made a foray in to a handheld remote with a screen several years ago, but it was ultimately retired. Sonos’ expertise is in sound, not really displays. I think they’d rather have you rely on a mobile device as a controller for your Sonos system.

All that being said, I really have no idea what Sonos’ plans for the future are. They could easily choose to announce something this week, but I’d be terribly surprised. And they tend not to announce products until weeks before shipping, likely to maximize the PR cycle of reviews and the like. Take a look, for instance, at the Sonos Ace. But as to what their next ‘device’ is, your guess may be better than mine. 

I see that Best Buy is having a sale on Sonos products. New items coming soon perhaps?

You may want to look at history. As I recall, but don’t keep track, there is often a sale around this time of year.
