Go? This is awesome to hear. Unlike Android, Glass will be an instant win for us Gophers. ( Well, once they have crossed 1m+ devices-sold so that the potential audience for hackery becomes actually interesting )
This could be a chance for Go to become more mainstream, if there wasn't so many languages supported, but I guess is not Google's agenda to disseminate their own lang.
I believe the Go library is automatically generated off the API, effectively just extending the existing Go/Google API client library. Which is not to necessarily down play it in any way (I love Go!), but just that it's not vastly exciting.
