This looks like a viable competitor to the recently announced HA Voice Preview hardware. Looks like it’s sold out at this point but there will be more coming. More microphones, presence detection and a builtin amplifier to run fairly substantial speakers.

I hope it’s not just a coincidence. I would love to see Home Assistant as a smart speaker platform progress.
