This is a miscommunication and they are actually referring to Silicon Dust and the upcoming capabilities of HDhomeRun , not Google.

Nvidia demoed an external over-the-air HD tuner and antenna that plugged into the back.

Hmm. Bummer. I suppose that's not a bad option. Hopefully they update their campaign with relevant androidtv info.
