If you didn’t buy into the 3D render of the Huawei-made Nexus, here's some more solid proof – live photos of the device itself.
The back design features a raised ridge for the camera and a round fingerprint sensor on the metal back. The Nexus 6 (the name feels uncertain since it has a 5.7" screen) measures 159.4 x 78.3 x 6.6mm, but thickness goes up to 8.5mm where the camera is.
On the front two speakers flank the QHD screen (1,440 x 2,560px). Not seen here, but at the bottom of the phone is a USB Type C port. The third image above is an early prototype with a plastic body.
We're also expecting a 5" Nexus from LG, you can see it rendered in 3D here. It features a similar design and similar features.
