Are there still any advantages to having a Google TV device though?
One thing that seems super promising about Google TV is the ability to control Netflix and Youtube videos directly from my Android phone and tablet, without streaming to the TV (which would suck up lots of batter power) because the TV has its own Android system. Will the same be possible with Chromecast or does Chromecast always stream via wifi?
Chromecast is directed by your device, but it is pulling it's data from the cloud, not directly from your device. That gets weird when you have them sync'd (such as youtube, if you're actively controlling it), but if you start a Netflix movie, you don't have to have it playing on your device for it to play in the cloud. I can see advantages to having Google TV over Chromecast, but not in a way that would justify having both, and they're really at two very distinct price points, so I view Chrome as the more practical version for most mainstream homes, with Google TV being for a user who wants a bit more control over the entire system. GTV will provide options that Chromecast does not, and have ways of providing the same features as Chromecast, in a way, but not in the same way. If that makes sense...
