I don't see any indication that it will stream anything aside from Amazon music. I don't see where they are touting any 3rd party integration. I'm not sure how this is supposed to scare SONOS, us, or anyone else. It's Amazon creating another angle on gaining more customers and information.
The TV tuner/DVR looks decent though. I wonder if they will allow Android TVs to link for streaming. I wouldn't want to have to buy a FireTV. I'll stick with my TiVo if that's the case.
