Clues have been circulating about Google's plans for a new VR headset in recent weeks. Now, the Wall Street Journal reports that Mountain View is working on a second virtual reality device. Unlike the headset we've seen tipped already, the second gadget is said to be a standalone unit that doesn't require a phone or PC in order to work. If this is true, it will be the first device to function without being connected to a computer or mobile device. A few days ago, a report surfaced stating that Google had a new headset in the works that would be a much more advanced version of Cardboard, but would still use a handset to drive the visuals.
