Ok, we might need to bump this into a new thread, because I'm really excited about the rumors flying around.
Specifically, my head exploded when I heard "multi room audio." I don't expect this new Chromecast to cost as little as the old one (though it might), but there's no way it'll cost as much as a Sonos. If I can pair a $35-50 Chromecast with the speakers I have already and get something at least approximating a Sonos, I'm going to be thrilled! I know that a Sonos can do so much more, but what it can't do is podcasts (they say they can, but no, they cannot). I really want this feature to be real so I can finally get the multi-room podcast setup I've been waiting for!
