Tomorrow evening at I/O we will learn more about Google Identity, which will likely replace their current Google Plus Sign-in APIs. Those APIs presented last year basically forced everyone to have Plus account users if they wanted to use Google as an Identity Provider. These screenshots look like the implementation for the 'Sign in with Google Identity' for both Android and Chrome. Looking forward to this, I love the Cloud Endpoints APIs, but had problems getting users to use them, since they had Plus forced onto them.
