According to 9 to 5 Google  It appears that Glass II has already been distributed to the company's Glass at Work enterprise partners.

The new model can fold up like a traditional pair of glasses and is more rugged for outdoor use. It still sports a small screen to the upper right of the user's vision, rather than displaying an image in the centre of one's view like the ODG R7 or Microsoft HoloLens.

One source said the update would cost much less than the original Glass' $1,500 price tag, to stay competitive with other smart glasses in the enterprise.

The focus for now is all about enterprise-specific augmented-reality applications, because those markets are ready and willing to buy and try smart glasses, rather than the consumer use cases that originally surrounded Glass' launch.
