I'm not sure what it means for the future of Glass, but doesn't the title and most of the content of the article undermine that it's being moved to an actual product division?
Edit: "Glass at Work has been growing and we’re seeing incredible developments with Glass in the workplace. As we look to the road ahead, we realize that we’ve outgrown the lab and so we’re officially “graduating” from Google[x] to be our own team here at Google. We’re thrilled to be moving even more from concept to reality." https://plus.google.com/+GoogleGlass/posts/9uiwXY42tvc
