Back in March, I told you that Sonos is working on a second-generation Move speaker due for release this year. And now, as spotted by Janko Roettgers, the upcoming portable speaker has made its way through the FCC. The filing matches up with my earlier report and identifies the next Sonos hardware product as model S44.
The FCC documentation also confirms one key upgrade that I mentioned in March: the Move (Gen 2) will support Bluetooth and Wi-Fi at the same time instead of making you toggle between them like the original speaker did (via a switch on the back). As a result, just like the Roam, Era 100, and Era 300, the next Move will let you play something over Bluetooth and then relay that audio to the rest of your Sonos system.
