It was obvious from the endless criticism the first Google Glass received that Google would have to do something different with the device’s successor, but the company might be taking things even further than expected by doing away with glass entirely. According to the Information, there will be three different Google Glass 2 models, two of which won’t actually have a glass display, though not much else is known about how they’ll work. We do know that one of them will be geared towards enterprise consumers, while another will be geared towards athletic users.
