There's a new Nexus in town (another one) today, and this one's headed straight for the big screen: as in, your TV. The Nexus Player runs Android TV with a 1.8GHz quad-core Intel Atom processor and talks to the web via a 2x2 AC Wi-Fi connection (there is no ethernet port). It's built in "collaboration" with ASUS.
Connecting to your TV is accomplished via HDMI. The Nexus Player will ship with full Google Cast (aka Chromecast) capabilities baked in, essentially negating the need for a Chromecast on the connected TV.
