I guess they've just focused on getting the functionality available on devices you can already find (Android and iOS devices, TVs like the newer Sonys that run AndroidTV, etc). I see the appeal of a standalone device but I find that lots of times, the response may not translate well into audio-only so having a screen helps when you ask something and the best answer is a graph, text, or image. Just a guess though. I'm surprised that wasn't included in that rather pricey wifi router they launched recently. It has a decent sized speaker in it but perhaps they decided not to enable it just yet. My guess is that they wanted to start selling the wifi routers but didn't think the voice stuff was up to snuff for a consumer application/selling point just yet.
