Yep, called it.
Sonos One ($199) officially announced for release on Oct 24. Here's the kicker: Sonos is says they'll add AirPlay2 support in '18
Furthermore, Amazon announced a new Echo ($99) which includes a subwoofer and Echo Plus ($149) which then tacks on a home automation hub, and a free Hue lightbulb (~$35 value).
And if you think Apple is the premium option, Google just announced the Home Max ($399) which looks better designed, includes Bluetooth+Aux in+wireless audio and a free 1yr Youtube Red (~$120 value).
Remind me again what the HomePod's selling point was?
