My understanding is that it's still borg. All the cool features from omega were backported into borg, since they were needed to support (insert product here), and in the end some of the omega team got an OK to write and open-source kubernetes based on the findings from omega. When I left, the big ongoing project in that space was an effort to replace babysitter (most people in Google do not have to worry about babysitter, and for 98% of the time, I didn't, but the 2% where I needed to meant that I kept myself informed of changes in that space).
